Polls

President Obama pulled into a tie with Mitt Romney in 12 swing states that will play a key role in determining the 2012 election, according to the latest Purple Poll.

Mitt Romney is leading President Obama in Michigan, according to a poll released Sunday by the Detroit Free Press.

Newt Gingrich leads the field of GOP presidential candidates, although the former House Speaker is in a statistical tie with Mitt Romney, according to the latest USA Today-Gallup poll.

While Latino voters are still more likely to vote for a Democrat, President Obama could have his work cut out for him in protecting this part of his core constituency against a surging Republican candidate, according to a poll released Thursday.

Newt Gingrich surged 11 percent in a Fox News poll released Wednesday night, taking the lead over former front-runner Mitt Romney.

Herman Cain leads the Republican presidential field in Iowa, according to a new poll released Thursday. 

The Iowa State University/Gazette/KCRG poll found that the former Godfather's Pizza CEO leads the GOP field in Iowa with the support of 24.5 percent of Republican voters. Cain is followed by Ron Paul with 20.4 percent of the vote, then Mitt Romney with 16.3 percent. 

The poll's findings are somewhat in contrast with a number of recent national polls that found Cain's recent front-runner or near-front-runner status disappearing in light of allegations that he sexually harassed a number of women while he was president of the National Restaurant Association in the 1990s.

Newt Gingrich seemed to take Cain's place in the lead of the GOP field either just behind or even ahead of Mitt Romney. But the Iowa poll found Gingrich near the back of the pack in the coveted primary state. The poll found Gingrich with 4.8 percent of Republican voters, behind Rick Perry with 7.9 percent and Michele Bachmann with 7.6 percent.

According to the poll, though, Gingrich leads Rick Santorum and Jon Huntsman. The poll found Santorum with 4.7 percent and Huntsman with no support.

The poll surveyed 979 Republican voters and 277 independents and was taken from Nov. 1-13, after the first sexual harassment allegations against Cain broke in late October.

Newt Gingrich is virtually tied with President Obama among registered voters, according to a new national poll.

Allegations of sexual harassment continue to bruise the Herman Cain presidential campaign, with a new poll showing a 17 percent rise in those who see the candidate unfavorably as he continues to lose ground in the Republican contest.

More Americans perceive Cain unfavorably — 44 percent — than favorably — 29 percent — according to a new poll from ABC News and The Washington Post. And Cain's favorability numbers are down in nearly every demographic group, the result of voters who were previously undecided about the former Godfather's Pizza CEO breaking against him.

Of those surveyed, 44 percent believed the women who accused Cain of sexual harassment, while only a third said they believed Cain's adamant denials. Sixty-nine percent of those surveyed said that the allegations were a "serious matter."
