President Obama is tied with or trailing a majority of his potential Republican 2012 challengers, a poll released Thursday shows.

Former Arkansas governor Mike Huckabee (R) and former Massachusetts governor Mitt Romney (R) held the strongest leads, at two and three points over Obama, respectively.

Arizona Gov. Jan Brewer (R) was the only potential GOP challenger that Obama solidly beat.

The survey included former Alaska governor Sarah Palin (R) and former House Speaker Newt Gingrich (R).

Conducted July 9-12 by Public Policy Polling, it showed the five potential GOP candidates faring better in individual match-ups for the presidency than their own favorability ratings would suggest.

42 percent of respondents had an unfavorable view of Newt Gingrich (R), but running against Obama, the former House Speaker still led the president by one point. Former Alaska governor Sarah Palin (R) is a similar case: 52 percent view her unfavorably, but she polled equally to Obama in an individual horserace, at 46-46.

"This poll tells us less about 2012 and more about current public opinion of Obama," says Dean Debnam, president of Public Policy Polling. "Voters are unsatisfied with Obama and are calling for change."
