 With the first debate less than two weeks away, Donald Trump and Hillary Clinton are in a tight race for the presidency nationally. Clinton has just a 2-point edge in a two-way match-up among likely voters. The race is tied when third party candidates are included. Among the broader electorate of registered voters, Clinton leads Trump by five points. 
 
 One disadvantage for Clinton is diminished voter enthusiasm. Democrats are less enthusiastic about voting now than they were in August. 
 
 More than four in 10 voters think each presidential candidate should release more of their medical records. This poll was conducted before either candidate’s recent release of medical information. 
 
 With Election Day just under eight weeks away, the race for President nationwide is tight. In a two-way match-up, Clinton has a slim edge over Trump, 46 - 44 percent among likely voters who support or lean toward a candidate. 
 
 This is the first national poll in which CBS News and the New York Times have measured the presidential race among likely voters. The measure for likely voters takes into account voters’ reported intent to vote, enthusiasm about voting and other factors that historically affect an individual’s decision to vote. 
 
 Among the broader electorate – registered voters nationwide – Clinton leads Trump by five points, 46 percent to 41 percent. 
 
 When third party candidates Gary Johnson and Jill Stein are factored in, the race is tied, with Trump and Clinton each getting the backing of 42 percent of likely voters. While Clinton and Trump retain most of their support when Johnson and Stein are included, slightly more of Clinton’s supporters move to Johnson or Stein, compared to Trump’s supporters. 
 
 Among registered voters, Clinton has a slight edge over Trump in a four-way contest. 
 
 Most Clinton and Trump voters say they’re sticking with their candidate. Ninety-two percent of Trump voters and 94 percent of Clinton voters say their choice is set. Few say they will change their minds before the election. 
 
 Enthusiasm and Strength of Support 
 
 Thirty-six percent of registered voters overall now say they are very enthusiastic about voting, the same as a month ago. But one disadvantage for Clinton is that enthusiasm among Republican voters has remained steady, while enthusiasm among Democrats has dropped. Among Democratic voters, the percentage that is at least somewhat enthusiastic has dropped from 77 percent in August to 64 percent today, while the percentage of Democrats who are very enthusiastic has dropped nine points – from 47 percent to 38 percent. 
 
 More specifically, Trump supporters are more excited about voting than Clinton’s supporters are. Forty-five percent of Trump voters say they are very enthusiastic about voting, compared to 36 percent of Clinton backers who feel that way. 
 
 Just over half of each candidate’s voters say they strongly support their candidate, but for many, support is not so strong - including a quarter who are voting for their candidate because they dislike the other choice. 
 
 Who’s Supporting Whom? 
 
 Trump now garners support from just under nine in ten Republican voters, as does Clinton among Democrats. 
 
 A look at the candidates’ demographic support also illustrates why the race is close. A gender gap remains: Trump has a double-digit lead over Clinton among men, while Clinton is ahead by a similar margin among women. Trump continues to struggle with African American voters but has an advantage over Clinton among whites. 
 
 Whites without a college degree are strong supporters of Trump (58 percent back him), while Clinton leads Trump among white voters with a college degree. 
 
 Clinton is ahead of Trump among voters under 30 but she is not getting the level of support Barack Obama received in 2012. 48 percent of young voters are currently backing her, while Obama won 60 percent of the young vote in 2012. Only 29 percent of young voters are supporting Trump, but 21 percent say they’ll vote for someone else or won’t vote. 
 
 The Candidates’ Medical Records 
 
 After Clinton’s bout of illness at the 9/11 ceremony and the announcement of her pneumonia diagnosis, more than four in 10 voters think each presidential candidate should release more of their medical records. About as many think the candidates have released enough information about their health already. The poll was conducted before either candidate’s recent release of medical records. 
 
 Over half of Republicans think Clinton should release more medical records concerning her health, but 52 percent think their nominee has released enough information already. Among Democrats, most (53 percent) say Clinton has released enough health information already, but want Trump to release more of his records. 
 
 This poll was conducted by telephone September 9-13, 2016 among a random sample of 1,753 adults nationwide, including 1,433 registered voters. Data collection was conducted on behalf of CBS News and The New York Times by SSRS of Media, PA. Phone numbers were dialed from samples of both standard land-line and cell phones. 
 
 The poll employed a random digit dial methodology. For the landline sample, a respondent was randomly selected from all adults in the household. For the cell sample, interviews were conducted with the person who answered the phone. 
 
 Interviews were conducted in English and Spanish using live interviewers. 
 
 The data have been weighted to reflect U.S. Census figures on demographic variables. 
 
 The error due to sampling for results based on the entire sample and the sample of registered voters could be plus or minus three percentage points. The error for subgroups may be higher and is available by request. The margin of error includes the effects of standard weighting procedures which enlarge sampling error slightly. 
 
 The sample of likely voters is modeled among registered voters (N=1,433), assigning each respondent a probability of voting based on their responses. The margin of error for the sample of likely voters is plus or minus three points.

 Hillary Clinton leads Donald Trump by five points in a head-to-head matchup in the latest national poll of likely voters from Quinnipiac University out Wednesday, with the advantage narrowing to just two points in a four-way race. 
 
 Matched against only Trump, 48 percent said they would vote for Clinton, with 43 percent choosing the Republican nominee, 3 percent picking someone else and 6 percent undecided. Clinton led by a larger margin in the previous Quinnipiac survey conducted in August, 51 percent to 41 percent. 
 
 Story Continued Below 
 
 Regardless of whom they are supporting, majorities voters likely to cast their ballot for Clinton or Trump said their main reason for supporting their candidate was more in opposition of the other option than liking their choice. More than half—54 percent of Clinton supporters said opposing Trump was their main reason for backing the Democratic nominee. Approximately two-thirds of likely Trump voters—66 percent—said their main reason for supporting him is because they opposed Clinton. 
 
 The latest results come as other state and national polls show similarly tightening margins between both major candidates, who have traded words in recent days over concerns about transparency and health. The Quinnipiac poll began last Thursday, a day after the Commander in Chief Forum, and remained active in the field until Tuesday, after days of public attention on Clinton's health following her early departure from a 9/11 memorial on Sunday and subsequent revelation that she had been diagnosed with pneumonia last Friday. 
 
 Asked whether they thought the election would be close or one of the candidates would win in a landslide, 69 percent chose the former and 22 percent the latter. 
 
 Republicans and Trump supporters were more likely to say the election will be close, while more Democrats and Clinton supporters said their candidate would prevail with ease. 
 
 Regardless of the candidate they are supporting, nearly six in 10 likely voters—58 percent—said Clinton would win in November, while 31 percent said Trump would be elected. 
 
 The usual racial, educational and gender gaps persist in the latest poll, with Clinton holding the support of 54 percent of women in the head-to-head matchup compared to 36 percent for Trump, who received the support of 50 percent of men to Clinton’s 41 percent. Among white voters, Trump leads 51 percent to 41 percent, while among non-whites, Clinton has a 47-point edge of 66 percent to 19 percent. 
 
 Among whites holding college degrees, Clinton leads 50 percent to 44 percent, while Trump leads among whites without degrees, 59 percent to 33 percent. 
 
 In the four-way ballot test, which followed the head-to-head matchup in the list of questions read to likely voters, Clinton received 41 percent to Trump's 39 percent. Libertarian nominee Gary Johnson received 13 percent, while the Green Party's Jill Stein took 4 percent, with 3 percent undecided among those choices. 
 
 In order to reach the primetime presidential debates, the first of which is scheduled for Sept. 26, third-party candidates must receive an average of 15 percent support in five national polls; however, the Quinnipiac survey is not one of them. 
 
 A separate question in the survey showed some support for Johnson’s inclusion in the debates, with 57 percent saying he should be included and 37 percent saying he should not. Support for Johnson’s inclusion was highest among independents (66 percent to 30 percent) and higher among Clinton supporters (60 percent to 33 percent) than Trump backers (50 percent to 46 percent). 
 
 The poll was conducted Sept. 8-13, surveying 960 likely voters nationwide via landlines and cellphones. The overall margin of error is plus or minus 3.2 percentage points. ||||| (CNN) Hillary Clinton holds commanding leads over Donald Trump in a trio of states that the GOP nominee has made central to his White House bid, according to polls released Thursday following both party's national conventions last month, and has maintained an advantage in the perennial swing state of Florida. 
 
 In New Hampshire, Pennsylvania, and Michigan -- states that have trended Democratic in recent elections, but whose economics and demographics seem to pose an opening for the GOP nominee -- Clinton has made strides in improving her favorable ratings, while Trump remains challenged by high unfavorable ratings and resistance from a significant portion of Republicans. 
 
 New Hampshire 
 
 A new poll of New Hampshire shows Clinton with a commanding 15-point lead over Donald Trump, finding Granite State Democrats coalescing around their nominee after their convention while state Republicans remain resistant to Trump. 
 
 Clinton leads Trump 47% to 32% among likely New Hampshire voters, according to the poll from WBUR , with third-party candidates Gary Johnson and Jill Stein included. Matched up one-on-one, Clinton's lead grows to 17 points, 51% to 34%. 
 
 Both candidates continue to suffer from challenging unfavorable ratings, though Clinton has made strides improving her marks following the conventions. The Democratic nominee now breaks even, with 45% saying they view Clinton favorably to 45% who say the opposite -- up from a -23 spread in a WBUR poll from May. Trump is viewed favorably by 29% of likely New Hampshire voters, against 60% who have an unfavorable opinion -- a slight decline from May. 
 
 The poll found also that Clinton receives the support of 86% of Democrats and 14% of Republicans, while Trump is backed by just 63% of Republicans and 4% of Democrats. 
 
 The WBUR survey also asked likely New Hampshire voters what they thought about each party's national conventions. Fifty-six percent said they thought Clinton emerged from the convention "much stronger" or "a little stronger," compared to 39% who said the same about Trump and the RNC. 
 
 The poll also found Democrats with an edge in the state's U.S. Senate race. Democratic Gov. Maggie Hassan leads incumbent GOP Sen. Kelly Ayotte 50% to 40%. New Hampshire is among a few close races in swing states in a year where control of the Senate could come down to just one or two changing seats. 
 
 The WBUR New Hampshire poll was conducted from July 29 through August 1, and surveyed 609 likely New Hampshire voters. The margin of error is +/- 4 points. 
 
 Pennsylvania 
 
 In Pennsylvania -- a Democratic-leaning Rust Belt state that Trump has vowed to put in play for the GOP this election -- another poll released Thursday showed Clinton leading Trump by double digits. 
 
 Clinton leads Trump 49% to 38% among likely Pennsylvania voters, according to the Franklin and Marshall College poll . Her lead swells to 13 points, 47% to 34%, with Johnson and Stein included. 
 
 Clinton's lead in Pennsylvania was buttressed by the Democratic National Convention. The poll found that 62% of those who watched the DNC said they were more likely to vote for Clinton. Forty percent of those who watched the Republican convention said it made them more likely to vote for Trump. 
 
 Both Clinton and Trump struggle with high unfavorable ratings among likely Pennsylvania voters, but as in New Hampshire, Clinton has an advantage over Trump on this measure. Forty-seven percent said they view the Democratic nominee favorably to 49% who view her unfavorably, while Trump's spread -- 33% favorable to 62% unfavorable -- is further underwater. 
 
 Likely Pennsylvania voters favor Clinton over Trump on the question of who has better judgment and experience, and who is more prepared to handle foreign policy and terrorism. But Clinton and Trump run about even on the question of who would better manage the economy. 
 
 Consistent with previous presidential elections in Pennsylvania, the Republican nominee's biggest leads are in the southwest region of the state, while Clinton's advantage is in the northeast, most notably in Philadelphia. 
 
 The Franklin and Marshall College poll of Pennsylvania was conducted from July 29 through August 1. The poll surveyed a random sample of 661 registered voters with a margin of error of +/- 4.8 points, and 389 likely voters with a margin of error of +/- 6.3 points. 
 
 Michigan 
 
 Another battleground poll released Thursday -- Michigan -- also found Clinton holding a significant lead over Trump. 
 
 Clinton is ahead of Trump by 9 points, 41% to 32%, among likely Michigan voters, according to a Detroit news/WDIV-TV poll . Clinton's lead is smaller, 6 points, without third-party candidates included. 
 
 Pollster Richard Czuba told the Detroit News the survey found a "shocking" Clinton lead in typically reliable Republican areas in west and southwest Michigan, where she carries leads of 5-6 points. And according to the poll, 30% of self-identifying Michigan Republicans are not backing Trump. 
 
 Trump's struggles in the state's conservative strongholds are attributable in part to Libertarian nominee Gary Johnson. The poll found that in those west and southwest regions of Michigan, critical for flipping Michigan red, Johnson is drawing 10% and 16% support, respectively. 
 
 The poll also found a majority of Michigan voters -- 61% -- say Trump is "ill-prepared to be commander in chief." 
 
 The Detroit News/WDIV-TV poll was conducted from July 29 through August 1, surveying 600 likely Michigan voters. It has a margin of error of +/- 4 points. 
 
 Florida 
 
 A new Florida poll also found Clinton leading, though the Democratic nominee's edge there is slimmer. 
 
 Clinton beats Trump 48% to 42% among likely Florida voters, according to the survey from Suffolk University . She leads 43% to 39% when third-party candidates are included. 
 
 Both candidates score net negative favorability ratings, though again, Clinton's numbers are marginally better. Half of likely Florida voters said they have an unfavorable opinion of Clinton, while 44% said they have a favorable opinion of the candidate. Trump is viewed unfavorably by 54% of respondents and favorably by 37%. 
 
 The Suffolk poll also found that majorities -- 57% -- said the country was on the wrong track, and that they felt less safe than 5-10 years ago. 
 
 Most likely Florida voters reported having negative views of the 2016 race. More than half -- 53% -- say they feel "alarmed" when they think about the presidential election, compared to just 28% who said they were excited. 
 
 And asked to rank the issues shaping the race, Floridians listed terrorism and national security as the most important, followed by jobs and the economy, and the selection of Supreme Court nominees. 
 
 The Suffolk University poll sampled 500 likely Florida voters from August 1 through 3. It has a margin of error of +/-4.4 points. ||||| Democratic presidential nominee Hillary Clinton leads Republican Donald Trump by six points among likely voters heading into the first presidential debate on Monday, according to a brand-new national NBC News/Wall Street Journal poll. 
 
 The survey – which was conducted after Clinton’s return to the campaign trail following her bout with pneumonia – shows a bigger advantage for the secretary of state than did polls taken during the heightened scrutiny of her health. 
 
 It also finds that Clinton is running nearly even with Trump when it comes to voter enthusiasm. 
 
 “Despite arguably the worst few weeks of her candidacy, the fundamentals still point toward a Hillary Clinton victory,” says Democratic pollster Fred Yang of Hart Research Associates, who conducted the survey with Republican pollster Bill McInturff of Public Opinion Strategies. 
 
 McInturff adds, “Donald Trump has closed the margin since August, but as we head towards the debate, still needs to push this campaign closer. The good news for him is the electorate narrowly agrees with him that America has lost ground and wants to see a change in direction.” 
 
 In a four-way horserace, Clinton gets support from 43 percent of likely voters and Trump gets 37 percent, while Libertarian nominee Gary Johnson is at 9 percent and the Green Party’s Jill Stein is at 3 percent. 
 
 In a head-to-head matchup without those third-party candidates, Clinton’s advantage expands to seven points, 48 percent to 41 percent. This is the NBC/WSJ poll’s first general-election poll of likely voters in the 2016 race. 
 
 Among the broader electorate of all registered voters, Clinton is ahead of Trump by five points in the four-way contest, 42 percent to 37 percent – down from Clinton’s nine-point lead in August. 
 
 And in a two-way race, Clinton’s edge among registered voters is seven points, 48 percent to 41 percent – also down from nine points in August. 
 
 Here, Clinton has the advantage with African American voters (81 percent to 7 percent), women (51 percent to 37 percent) and those ages 18-34 (50 percent to 34 percent), while Trump is ahead among men (46 percent to 44 percent) and whites (49 percent to 41 percent). 
 
 But the poll reveals a familiar pattern among white registered voters: Those without a college degree break for Trump, 53 percent to 35 percent, while those with college degrees tilt in Clinton’s favor, 49 percent to 43 percent. 
 
 Clinton runs nearly even with Trump on voter enthusiasm 
 
 Seventy-eight percent of Trump’s voters say they are highly interested in November’s general election – registering either a “9” or “10” on a 10-point scale – versus 75 percent of Clinton voters who say that. 
 
 What’s more, 68 percent of Clinton voters respond that they will “definitely” vote for her, compared with 66 percent of Trump supporters who say that about the New York businessman. 
 
 And 50 percent of Clinton voters say their vote is more for Clinton, while 44 percent of them say their vote is more being against Trump. 
 
 That’s compared with 41 percent of Trump voters who say their vote is more for Trump, versus 51 percent who say it’s more being against Clinton. 
 
 Many voters still want change 
 
 Despite Clinton’s lead in the NBC/WSJ poll, Trump’s advantage is that many voters still want change. 
 
 By a 49 percent-to-47 percent margin, registered voters say they prefer a president who will bring major changes to the way the government operates, even if those changes might be unpredictable – though that margin is less than it was back in July. 
 
 And 48 percent of voters agree with Trump’s statement that America is losing ground and the economy hasn’t improved enough. That’s compared with 45 percent who agree with the Clinton message that the country is making progress and the economy has come back.

 Trump holds the advantage on economy, Clinton on all other issues 
 
 Asked which candidate is better on the economy, 46 percent of registered voters say Trump, while 41 percent pick Clinton. 
 
 But Clinton leads on every other issue the poll tested – on being in charge of nuclear weapons (51 percent to 25 percent), on being a good commander-in-chief (48 percent to 33 percent), on dealing with immigration (50 percent to 39 percent) and on terrorism and homeland security (44 percent to 43 percent). 
 
 Clinton also holds the advantage over Trump on being knowledgeable and experienced enough to handle the presidency (60 percent to 23 percent) and on having the right temperament to be president (56 percent to 23 percent). 
 
 But Trump holds the edge on being honest and straightforward (41 percent say Trump is better here, versus 31 percent who say Clinton is). 
 
 Obama’s job rating remains above 50 percent 
 
 The poll also finds President Barack Obama’s job-approval rating at 52 percent – unchanged from last month. Indeed, this is the fifth-straight NBC/WSJ poll in which his job rating has been above 50 percent. 
 
 And the poll shows Democrats enjoying a three-point advantage on which party should control Congress – 48 percent of registered voters prefer Democrats in charge, while 45 percent want the GOP in control. 
 
 Democrats held a four-point advantage on this question a month ago. 
 
 The NBC/WSJ poll was conducted Sept. 16-19 of 1,000 registered voters – by both landline and cell phone interviews – and it has an overall margin of error of plus-minus 3.1 percentage points. Among the 922 likely voters the survey interviewed, the margin of error is plus-minus 3.2 percentage points.
– The race for the White House does indeed appear to be tightening. A new CBS/New York Times national poll shows Hillary Clinton with just a 2-point lead over Donald Trump among likely voters, 46% to 44% in a two-candidate race, with a 3-point margin of error. With Gary Johnson and Jill Stein in the mix, Clinton and Trump are neck-and-neck at 42% each. Among all registered voters, Clinton fares better. She has a 5-point lead over Trump, 46% to 41%, in a two-candidate race, and a 2-point lead, 41% to 39%, with Johnson and Stein included. But her lead is still diminshed, and her recent bout with pneumonia may have played a role. Just 38% of Democrats said they were excited about voting in the poll of 1,753 from Friday to Tuesday, down from 47% in August. That's compared to 64% of Republicans, down from 77%, though nearly all Trump and Clinton supporters said their minds were made up. "Not since Trump's post-Republican National Convention bump has the GOP nominee seemed to be in such a strong position," though he's "still the underdog," writes David A. Graham at the Atlantic. A Quinnipiac University national poll of 960 likely voters shows Clinton with a 5-point lead over Trump in a head-to-head battle, and a 2-point lead in a four-candidate race with a 3-point margin of error, per Politico.
