There are a lot of predictions floating around out there about who will win the presidential election on Tuesday. So why not round them all up in one place? 
 
 
 
 Place your bets, folks. 
 
 Here are the electoral vote predictions from various modelers, political scientists and pundits from around the Internet. All predictions are as of Monday evening. And yes, this will be a fun thread to revisit the day after the election: 
 
 Nate Silver, FiveThirtyEight: Obama 332, Romney 203. This appears to be the most likely scenario in Silver's model, which now gives Obama a 91 percent chance of winning and shows Florida as basically a tossup. "In order for Mr. Romney to win the Electoral College, a large number of polls, across these states and others, would have to be in error, perhaps because they overestimated Democratic turnout.," Silver writes. 
 
 Intrade: Obama 303, Romney 235. The betting markets also give Obama a 70 percent chance of winning as of Tuesday morning. The main difference from Silver's model is that Intrade gives Romney a fairly strong chance (65 percent) of winning Florida. 
 
 Washington Post's Outlook contest: There are a slew of different predictions here. Chris Cillizza of the Fix predicts a narrow 277-261 Obama win. Andrew Beyer, our horse-racing columnist, predicts a 284-254 Romney win. And Jason Samenow of the excellent Capital Weather Gang predicts a 281-257 Obama victory. 
 
 Sam Wang, Princeton Election Consortium: Obama 303, Romney 235. "In terms of EV or the Meta-margin, [Obama has] made up just about half the ground he ceded to Romney after Debate #1." 
 
 Drew Linzer, Emory University: Obama 326, Romney 212. "The accuracy of my election forecasts depend on the accuracy of the presidential polls," Linzer writes. "As such, a major concern heading into Election Day is the possibility that polling firms, out of fear of being wrong, are looking at the results of other published surveys and weighting or adjusting their own results to match." 
 
 Michael Barone, The Examiner: Romney 315, Obama 223. "Both national and target state polls show that independents, voters who don't identify themselves as Democrats or Republicans, break for Romney." 
 
 Ezra Klein, The Washington Post: Obama 290, Romney 248. "I have a simple rule when predicting presidential elections: The polls, taken together, are typically pretty accurate. Systemic problems, while possible, aren’t likely." 
 
 Larry Sabato, UVA Center for Politics: Obama 290, Romney 248. "Who could have imagined that a Frankenstorm would act as a circuit-breaker on the Republican’s campaign, blowing Romney off center stage for three critical days in the campaign’s last week, while enabling Obama to dominate as presidential comforter-in-chief, assisted by his new bipartisan best friend, Gov. Chris Christie (R)?" 
 
 Josh Putnam, Davidson College: Obama 332, Romney 206. "Everything above is based on a graduated weighted average of polls in each state conducted in 2012," Putnam wrote in explaining his methodology. "The weighting is based on how old a poll is. The older the poll is the more it is discounted. The most recent poll is given full weight." 
 
 Jay Cost, Weekly Standard: Romney victory. "For two reasons," Cost writes. "(1) Romney leads among voters on trust to get the economy going again. (2) Romney leads among independents." 
 
 Philip Klein, The Examiner: Obama 277, Romney 261. "I’ve given Romney the states that are essentially tied, in which he’s led in at least some recent polls. But in states where Romney has trailed in nearly all polls, and in some cases by a comfortable margin, I’m giving them to Obama." 
 
 Ross Douthat, New York Times: Obama 271, Romney 267. " In general, I think that the political class tends to overestimate the power of the Hispanic bloc, whose influence is growing more slowly than many pundits and strategists acknowledge. In general, I think that the political class tends to overestimate swing voters’ sympathy for strident social liberalism, and to imagine a lockstep support for legal abortion among female voters that doesn’t actually exist." 
 
 Simon Jackman, Stanford University: Obama 332, Romney 206. "The model uses poll data (and house effect corrections) to generate estimates of Obama and Romney levels of support in the states (and at the national level). The modeling is done simultaneously: if you will, there are up to 52 latent quantities (e.g., Obama support in 50 states, the District of Columbia, plus the national level) moving over time, with polls giving us (noisy) snapshots as to where the latent targets might be on any given day." 
 
 Dave Weigel, Slate: Romney 276, Obama 262. He originally had Romney winning Ohio. But, as he explained yesterday, he's not so confident about that anymore: "That was 48 hours ago. Since then, I've grown more bearish on the Republicans in Ohio, as the final reliable newspaper and college polls arrive. And since then I've spent lots of time with different Ohio voter groups, and been surprised by the power of the Ds. So, if you like, you can unskew the prediction." 
 
 Kenneth Bickers, University of Colorado and Kevin Berry, CU-Denver: Romney 330, Obama 208. "While many election forecast models are based on the popular vote, the model developed by Bickers and Berry is based on the Electoral College and is the only one of its type to include more than one state-level measure of economic conditions." (This model was last updated in October.) 
 
 Jamelle Bouie, The American Prospect: Obama 303, Romney 235. "[I]f Obama wins on Tuesday, the political science on debates will have won out; they can shift the short-term situation, but they don’t fundamentally change the direction of an election." 
 
 George Will, The Washington Post: Romney 321, Obama 217. " I guess the wild card in what I've projected is I'm projecting Minnesota to go for Romney. Now, that's the only state in the union, because Mondale held it -- native son Mondale held it when Romney was -- when Reagan was getting 49 states -- the only state that's voted Democratic in nine consecutive elections. But this year, there's a marriage amendment on the ballot that will bring out the evangelicals and I think could make the difference." 
 
 Ben Domenech, The Transom: Romney 278, Obama 260. "In sum, I see the bottom slipping out from under Obama’s feet, and a campaign hoping to hold on just long enough to salvage a slim victory, one where he is almost certain to lose the popular vote. He is underperforming among whites and independents, and particularly among those likeliest to vote. I have never believed in running the prevent defense, and Obama has been running it for months." 
 
 Markos Moulitsas: Obama 332, Romney 206. "Currently, national polling assumes a big dropoff from registered voters to likely voters. I don't believe that'll be the case, and we're certainly not seeing it in the early vote—Democratic turnout is up. And the RV models have been more accurate historically." 
 
 Karl Rove: Romney 285, Obama 253. He's got Romney winning Ohio, Iowa, Virginia, Colorado, and Florida. 
 
 Xu Cheng, Moodys' Analytics: Obama 303, Romney 235. Note that this prediction was made back in February: "This prediction is tied to the Moody’s Analytics current baseline forecast for U.S. growth, which assumes that most states will continue to recover at slow to moderate speeds." 
 
 James Pethokoukis: Romney 301, Obama 227. "Many pollsters are not catching the stratospheric GOP enthusiasm, particularly among voters of faith, in voting for Romney and Paul Ryan — not just against Obama and Joe Biden. In this way, the Bush-Kerry parallel from 2004 does not hold up" 
 
 Joe Trippi, Democratic consultant, Obama 303, Romney 235. Trippi sent in his by e-mail--he's going with these states. 
 
 Dick Morris, FoxNews: Romney 325, Obama 213. "It will be the biggest surprise in recent American political history," Morris said. "It will rekindle the whole question on why the media played this race as a nailbiter where in fact Romney’s going to win by quite a bit." 
 
 Jim Cramer, CNBC: Obama 440, Romney 98. Here's a tweet from Cramer: "No one is going to recall the guy who picks Obama by 10 electorals if it turns out to be 150 margin. Believe me." 
 
 Dean Chambers, UnskewedPolls.com: Romney 275, Obama 263. "Many others in the media project very favorable maps and projections for Obama but those doing so fail to realize or accept how heavily-skewed polls distort any average or analysis that relies on them." 
 
 A ton of predictions from CNN's pundits. You can see them all here. Paul Begala thinks Obama will win 297-241. Ari Fleischer thinks Romney will win with "minimum 271 EVs." And so on.

 After Mitt Romney selected his vice presidential running mate, and just days before the political conventions kick off next week, President Barack Obama maintains his advantage in the race for the White House, according to the latest NBC News/Wall Street Journal poll. 
 
 A Democratic ticket featuring Obama and Vice President Joe Biden gets support from 48 percent of registered voters, and a Republican ticket of Romney and new running mate Paul Ryan gets 44 percent. 
 
 These numbers are only slightly changed from July, when Obama led Romney by six points in the survey, 49 percent to 43 percent, suggesting a minimal bounce for Romney (if at all) after this month’s Ryan pick.

 While the state of the U.S. economy and the nation’s direction continue to pose significant obstacles for the president, the poll points to even steeper challenges for Romney, including concerns about his tax returns and a lack of support for his plans to overhaul Medicare. 
 
 “The election has moved from a referendum to a choice,” says Democratic pollster Peter D. Hart, who conducted this survey with Republican pollster Bill McInturff. “Mitt Romney is starting to accumulate a number of negatives on the personal front and issues front.” 
 
 Looking ahead to next week’s Republican convention, which begins on Monday in Tampa, Fla., Hart adds: “Mitt Romney has a lot of repair work to do with his image.” 
 
 NBC's Chuck Todd and the National Journal's Major Garrett discuss the latest NBC News/WSJ poll. 
 
 But McInturff argues that there’s still a path to victory for Romney, especially with Obama’s numbers below that all-important 50 percent threshold for an incumbent. 
 
 “When a guy gets stuck at 48 percent, it doesn’t mean they are out of the clear,” he says. “It means they are in an incredibly competitive campaign.” 
 
 The swing states, the demographics and the Ryan pick 
 
 In a smaller sample of voters living in 12 key battleground states – Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin – Obama leads Romney by three points, 49 percent to 46 percent. 
 
 That’s a narrower edge in these battlegrounds than the eight-point lead the president enjoyed in the June and July NBC/WSJ polls. 
 
 Looking inside the numbers, Obama continues to lead Romney among key parts of his political base, including African Americans (94 percent to 0 percent), Latinos (by a 2-to-1 margin), voters under 35-years-old (52 percent to 41 percent) and women (51 percent to 41 percent). 
 
 Romney is ahead with whites (53 percent to 40 percent), rural voters (47 percent to 38 percent) and seniors (49 percent to 41 percent). 
 
 And the two presidential candidates are essentially even when it comes to the swing groups of suburban voters, Midwest residents and political independents. 
 
 As for Romney’s selection of Ryan as his running mate, which was made on Aug. 11, the poll suggests that – so far – the pick has had less of an impact on voters than previous running mates have had. 
 
 President Obama touts his education policy, contrasting his budget proposal to GOP vice presidential pick Paul Ryan. Watch his entire speech. 
 
 Twenty-two percent say Ryan makes them more likely to vote for the presumptive Republican presidential nominee, while 23 percent say he makes them less likely to vote for Romney; 54 percent say the pick doesn’t affect their vote either way. 
 
 That margin (-1) is compared with Joe Biden’s in 2008 (+8), Sarah Palin’s in 2008 (+9 percent), John Edwards’ in 2004 (+21), and Joe Lieberman’s in 2000 (+13). 
 
 Ryan’s numbers come closest to Dick Cheney’s in 2000 (+2). 
 
 Moreover, in the poll’s feeling thermometer, Ryan’s favorable/unfavorable score stands at 33 percent/32 percent. 
 
 Hart, the Democratic pollster, attributes Ryan’s mixed numbers to today’s increasingly partisan divide, with Republicans backing him, Democrats opposing him and independents fairly divided. 
 
 Romney’s two challenges 
 
 According to the poll, Mitt Romney has two challenges heading into next week’s Republican convention in Florida: repairing his image and selling his proposal to overhaul Medicare. 
 
 NBC/WSJ poll: Voters split on Ryan 
 
 For starters, Romney continues to have a net-negative favorable/unfavorable score (38percent/44 percent) – which no other modern Republican presumptive presidential nominee has had. 
 
 What’s more, Obama bests Romney by 35 points (58 percent to 23 percent) on the question of which candidate is more likeable, and by 22 points (52 percent to 30 percent) on caring about average people. 
 
 In addition, a majority of voters (51 percent) view the former Massachusetts governor’s approach to issues as being “out of step” with most Americans’ thinking. By comparison, 54 percent say Obama’s positions are “in the mainstream.” 
 
 And by a 36 percent to 6 percent difference, voters say what they have seen, heard and read about Romney’s tax returns – he has refused to release returns prior to 2010 – has given them a more negative impression of the Republican candidate. Forty-one percent say it doesn’t make much of a difference. 
 
 Problematically for Romney, similar negative margins exist with swing voters like independents, suburban voters and Midwest residents. 
 
 “That is as much negative as anything that comes out in this poll,” Hart says of Romney’s tax returns. 
 
 Testing the Medicare debate 
 
 Another negative for Romney in the poll is his plan to make substantial changes to Medicare, the government health-insurance program for seniors. 
 
 When voters are given a description of the Romney-Ryan plan – that future seniors would receive a guaranteed payment that some call a voucher, and that these seniors could use it to purchase either private insurance or to have access in the traditional Medicare program – twice as many call it a bad idea (30 percent) versus good idea (15 percent). 
 
 However, 51 percent of voters said they have no opinion. 
 
 In a separate question, 34 percent of voters say they agree with the statement that Romney believes this Medicare proposal “is a good idea because it would strengthen Medicare and reduce government costs … by giving future seniors more control over their own health-care dollars.” 
 
 NBC/WSJ poll: Approval of Congress hits bottom 
 
 In contrast, 50 percent say they agree with the statement that Obama believes this proposal “is a bad idea because it would end Medicare as we know it by turning it into a voucher system giving seniors a set amount of money to pay for their health-care costs and leaving them to personally cover costs above this amount.” 
 
 What’s more, a plurality (39 percent) say that Medicare needs only minor modifications, versus 15 percent who believe it needs a complete overhaul, another 15 percent who think it’s OK the way it is and 27 percent who say it needs major changes. 
 
 And when asked which candidate is better on issues affecting seniors, 46 percent pick Obama and 34 percent choose Romney. 
 
 Obama’s own challenge: the economy 
 
 Yet Obama has challenges, too, and they’re the same ones that have dogged his campaign over the past year. 
 
 More than six in 10 believe the country is headed in the wrong direction, which is essentially unchanged from last month. 
 
 And just 36 percent believe the economy will improve in the next 12 months, though that’s up nine points since July’s poll. 
 
 Not surprisingly, Romney holds a six-point advantage over Obama (44 percent to 38 percent) on which candidate has better ideas on how to improve the economy.

 That said, 50 percent of voters in the poll believe the economy is recovering, and they’re split (46 percent to 46 percent) on whether the recent news about the economy has made them more optimistic or less optimistic. 
 
 The president’s overall job approval rating stands at 48 percent, and approval of his handling of the economy is at 44 percent. 
 
 The NBC/WSJ poll was conducted of 1,000 registered voters (300 reached by cell phone) from Aug. 16-20, and it has an overall margin of error of plus-minus 3.1 percentage points.
– It's Election Day—a day of reckoning not only for the candidates, but for America's pundits, including one recent lightning rod named Nate Silver. Silver's final prediction: President Obama has a 91.6% shot at winning, to Romney's 8.4%, though he emphasizes he expects a close contest. But the momentum has lately been in Obama's favor, and 19 battleground state polls yesterday showed Obama in the lead, while Mitt Romney led in just three, Silver writes in the New York Times. Silver sees Obama winning 314.6 electoral votes to Romney's 223.4, and believes the popular vote margin will be similar to George Bush's over John Kerry: two or three percentage points. Elsewhere in crystal-ball land, via the Washington Post: RealClearPolitics puts Obama up 48.8% to Romney's 48.1%; it sees Obama winning 303 electoral votes to 235 for Romney Intrade gives Obama a 72% chance of victory to Romney's 28% Jim Cramer at CNBC: Obama 440, Romney 98 (a bit of an outlier) Ross Douthat at the New York Times: Obama 277, Romney 261 Ezra Klein at the Washington Post: Obama 290, Romney 248 Drew Linzer at Emory University: Obama 326, Romney 212 Dick Morris of Fox News: Romney 325, Obama 213 Karl Rove: Romney 285, Obama 253 Larry Sabato, the University of Virginia: Obama 290, Romney 248 Sam Wang at the Princeton Election Consortium: Obama 303, Romney 235 George Will at the Washington Post: Romney 321, Obama 217 Mike Allen over at Politico, meanwhile, has a pointer for those looking to call it an early night: "Watch Prince William and Loudoun counties in Virginia's increasingly diverse DC exurbs. Old Dominion polls close at 7, and the Commonwealth tends to count pretty fast. Obama won both counties in 2008. Romney has to take back territory like that if he's going to win. Tell me who won Prince William and Loudoun, and I'll tell you whether we have President 45 or President 44, Part II."
