Are you telling me he's Black? Why didn't somebody tell me before I voted in 2008?

If Barack Obama loses re-election, he can blame bigoted white voters. That's an argument we've heard almost continuously since things started going wrong for the president, and we can expect to hear it until November and, if Obama does lose, for some time thereafter.

But wait. In 2008 Obama not only won but received a higher percentage of the vote than any candidate since 1988 and any Democrat since 1964. For Obama to lose this year, a lot of voters who supported him then will have to switch to the Republican nominee or at least stay home. Those prospective swing voters can't be antiblack bigots, can they? They voted for a black man in the last election.
