Bush has a residual negative effect that has lasted - and unfortunately, no matter how different a candidate is from Bush, being a southerner is a negative in 2012 because it reminds people. The accent, the swagger, the whole thing. Bush's problem was not Iraq so much as it was his FDR-lite approach to everything else, which gave way to the second coming of FDR (except with a pansy foreign policy) in Obama.
We need a Calvin Coolidge type candidate - one who's not afraid to slash taxes and spending, but sounds and looks intellectual. Christie is attractive for that reason, but because of his social views, it will be difficult for him to make it past a primary, so he should be vice president.
It reminds "non-southerners" of Bush. I don't think southerners have any problem with Haley or anyone else that "reminds them of Bush." You're just generalizing all southerners and sounding like a liberal media trying to paint everyone as anti-Bush. Its sounds like the mainstream media is out of touch. Haley has some of those issues, but He will win or lose on his own merits, not because of the past Bush administration. And Bush's wall street problem was that he enabled the risks, and that is what Coolidge did with his Laisezz-fair policy. You want someone who sounds and looks intellectual, then vote for Harvard Obama. Its a popularity contest and Haley will beat Romney in a popularity contest of the primaries.
