Bits of last night's debate keep popping back up into my brain, like Vietnam flashbacks. I don't know how we have not already posted this on Slog already, this morning: A Republican audience tearing the roof off a Myrtle Beach hall when Rick Perry says "South Carolina is at war with this federal government."

If everyone can hear the scary racism in your debate performance, does it go from dog whistle politics to just plain whistle politics?
