The biggest giveaway was the backwards B (if you can read it in the mirror, you're doing it wrong!)...that, and the sheer racist absurdity of a mugging-gone-political statement by a "large scary black man" in the middle of the whitest Italian side of town. I've read in reports that she's from College Station, TX. Having gone to A&M there, I can say that this is not all that surprising. Concentrated conservatism + youthful stupidity yields some impressive results in that town, so this is really par for the course.
McCain shouldn't catch flak for this, but he's going to anyways, sadly. Good thing that I believe both he and Obama have denounced her actions (though I question the sudden, public, personal interest Palin took in it with her phone call). I wonder if this girl realizes exactly how much she has hurt the very campaign she was trying to win sympathy for
