Obama's approval rating in the state is 49% with 45% of voters disapproving of him. The Democratic base stands pretty universally behind him at 89% approval and independents break slightly in favor of him by a 49/43 spread. Holding him below 50% is that he has virtually no support from Republicans, only 10% of whom approve of his job performance.
Obama's approval spread may only be +4 but his leads over all of his prospective Republican opponents exceed that. He's up 7 points on Mike Huckabee at 48-41, 9 points on Paul Ryan at 49-40, 10 on Mitt Romney at 48-38, 12 on Newt Gingrich at 51-39, and 19 on Sarah Palin at 54-35.
