When I read that I knew it would get a rise out of conservatives. You are right about Krugman. He's in his own world.
If the far left things McCain's abandoned them, they're stupid (but we knew that). I saw McCain on The Daily Show last week, and when he was asked about speaking at Liberty University, he made a bit of fun of Falwell.
If it's shrewd on McCain's part, there's not much more going on beneath the surface. He'll pretend to be a right-winger now, all the while winking at the left -- hey, I'm still that maverick who can anger up the rednecks! Just wait!
I'll pass.
