Republicans don't have to accept evolution, economics, climatology, or human sexuality, but I just watched a week of their national convention, and I need them to admit the historical existence of George W. Bush. If your party can run the nation for eight years and then have a national convention and not invite Bush, Cheney, Rumsfeld, Colin Powell, Karl Rove, or Tom DeLay, you're not a political movement, you're the witness protection program.
