UPI Poll: Obama up by 4 points on Romney 22 (UPI) -- U.S. President Barack Obama owns a 4-percentage-point lead over Mitt Romney in the United International Poll released Saturday. Nearly half -- 49 percent -- of likely voters asked named Obama, a Democrat seeking re-election, as the candidate respondents said they would support in November's election for president. Romney, the former governor of Massachusetts and Republican candidate for president, was listed by 45 percent of respondents. The figures, compiled by CVoter, are the same as those given last Sunday. The data represent a seven-day rollover. Among all voters, Obama's lead is 38.4 percent to 36.3 percent for Romney, with 11.1 percent listed as undecided. Another 8 percent said they won't vote Nov. 6 and 6.1 percent said their preferred candidate wasn't either Obama or Romney. The difference on the question of "Who do you think will grow the economy more in the next four years?" was narrow, with 41.1 percent of respondents naming Obama and 40.3 percent Romney. The economy remains foremost in respondents' minds as 39.6 percent gave "economic crisis" and 21.4 percent said "unemployment/job-related issues" were the most important of a series of issues that also included options such as the war on terror, international relations and education. The data represent responses from 973 registered voters reached by telephone over the seven-day rolling sample for general questions and 795 "likely voters." There is a margin of error of 3.5 percentage points.
