I still wonder how this guy was even elected Governor.
2-0-1-0. Highly common after a party-pickup presidential victory [2008] to reap, two years later, revenge for the party that flipped out of the White House. So, there was little in the way of standards. In some states you couldn't get away with it [U.S. Senate races in Colorado, Delaware, and Nevada]. In others [like this one], it wasn't a problem. (The more you consider it, Republicans were able to run big time on racism even though it wasn't necessary because it was their year. But let's see them try that again in 2012.)
But still, gubernatorial elections aren't as partisan as Senate ones and Florida is to some extent a swing State. With such a joke as a GOP candidate, I don't see how he managed to do so well. Maybe Rubio's coattails, but is that enough to explain ?
