Rick Perry threw his hair in the ring on Saturday. His entrance into the GOP presidential field can be a game changer. Perry can raise money as well as Mitt. He can rally the base as well as Michele Bachmann, and he will say or do anything—annnnnnnyyyyyyything—to win. And in today’s Republican Party, if you want to be the nominee you have to be willing to do some really crazy s–t…

Perry has flaws, huge flaws. Not the least of which is that he presided over the execution of one of his constituents, Cameron Todd Willingham, who was probably innocent. But I’m not sure that’s a liability in today’s Tea Party–obsessed GOP. There’s a legend in Lone Star politics that one of Perry’s Republican rivals in Texas tested the Willingham issue in a focus group. One Republican man, the story goes, squinted and said, “Well, I like that. Takes a lot of balls to execute an innocent man.” At that moment, folks say, Perry’s rival knew opposing him was fruitless.
