Barack Obama came close to pulling an upset victory in Montana in 2008, but it doesn't look like he'll be able to repeat his strong performance there next year. Only 39% of voters in the state approve of the job he's doing to 56% who disapprove, and he trails all of his GOP opponents by margins ranging from 2-10 points.
Obama's troubles in Montana are indicative of his broader issues with white voters. He's fallen a lot further with white voters than either African Americans or Hispanics so in states with pretty much all white populations like Montana, New Hampshire, Iowa, and Wisconsin he's doing a lot worse relative to 2008 than in states like North Carolina, Florida, and Virginia that have more diverse electorates.
Obama's doing very poorly with independents, only 36% of whom approve of him while 57% disapprove. And Republicans (93%) are far more united in their disapproval of him than Democrats (81%) are in their approval.
There's not a huge electability gap in Montana between the two Republican front runners. Mitt Romney leads Obama by 10 points at 50-40 and Newt Gingrich has an 8 point advantage at 50-42. Ron Paul matches Gingrich's 8 point lead at 48-40 and this is yet another state where he's the strongest candidates with independents, leading Obama 50-35 with them.
