I'm pretty confident the criticism will die down after awhile. Two days after McCain lost, the Conservatives are still fuming, and even by the end of Obama's first term I'm sure they'll find something to bitch about even if he's done a fantastic job.
You're right though. Racism is alive and well. Even more so, stupidity.
Not to get counter-racial on you, but I really love how suddenly ultra-conservative southern white people are playing the victims...suddenly the country is no longer being ran by one of their own and so the only possible outcome of all this is that he's somehow going to single-handedly convince a heavily white congress to pass a law that promotes the genocide of every Caucasian in the states.
