It looks like the Republican campaign has decided that there's nothing left to lose by going all-in with the muck-raking and dirt-slinging. Sarah "Failin'" Palin is trying to establish a new world record for Guilt By Association between Obama and the Weather Underground. For the record, I think I'm closer to Kevin Bacon than Obama is to 1960s domestic terrorists.
The biggest problem with this smear campaign, though, is Palin's ongoing incomprehensibility. When she says "turrist", I never know whether she means "terrorist" or "tourist". You'd think that the context would make it clear. But not in her case.
