GOP presidential hopeful Michele Bachmann is gaining ground in a new national poll, but the survey shows President Obama would have little trouble over all Republicans except Mitt Romney.

Romney, a former Massachusetts governor, is the choice of 25% of GOP primary voters in the latest poll from Quinnipiac University.

But the news among Republicans is Bachmann's surge to 15% behind Romney -- a jump from sixth place to second in the poll -- and the presence of Texas Gov. Rick Perry, who is the choice of 10% of GOP primary voters. He comes in fourth behind Sarah Palin, with 12%. Neither Perry nor Palin have decided yet on making the 2012 race.

"The question about Rep. Bachmann is whether she is the flavor of the month, like Donald Trump was for a while, or does she have staying power?" says Peter Brown, assistant director of the Quinnipiac University Polling Institute.

He also said Perry's showing indicates "he could be a serious contender if he decides to run." The Texas governor was not included in Quinnipiac's previous surveys.

Bachmann, Palin and Perry all are favorites with the Tea Party movement, Brown notes, which could be a factor in how the race for the GOP nomination finally shakes out. We should note that polls are a snapshot in time, and the picture now may not be the same when voters go to the polls.

Rounding out the GOP field for that party's nomination: Herman Cain (6%), Ron Paul and Newt Gingrich (5%), Tim Pawlenty (3%) and Rick Santorum and Jon Huntsman (1%). Thaddeus McCotter did not register in the Quinnipiac poll and 18% listed don't know or no answer.

In hypothetical matchups, Obama leads all in the GOP field and hits 50% or more against Bachmann, Palin and Perry. The Democrat's biggest challenge, according to the survey, would be against Romney.

Obama leads Romney, 47%-41%. That finding hasn't changed since Quinnipiac's poll last month.
