I actually might vote for Bush over Sharpton. Say what you want about reforming, but Sharpton spent many many years as the worst kind of scumbag, and I don't think he's entirely changed, even though he tries to appear as though he has.
Also, even though he's said a bunch of sensible things this year, in the past few weeks he's said a lot of terrible things. He even hinted that if elected he would immediately pull all troops out of Iraq WITHOUT waiting for an international/UN or homegrown Iraqi force to take over. I mean, holy shit, I don't think even solid antiwar liberals think that's a good idea.
