George W. Bush: Last white president?

I'm stealing this joke from a friend:

F: "Everyone's talking about how Obama's the first Black President, but not the fact that George W. Bush is the last white one."

Me: "Why's that?"

F: "Because, once you go Black, you never go back..."

Congratulations to President Obama, now please make us all proud. And thanks George: you gave us a more nationalized economy, expanded the powers of government to help and assist the needy, and paved the way for a Black president. I know it was a mistake, but that counts too.
