Upper Deck's press release didn't offer specific odds, but did promise they were "super-rare." I'll hold back a snide remark but that doesn't mean I'm not thinking something.
Seriously, though, what's with this obsession with Sarah Palin. At least when Obama shows up on a card, he's President. Palin's on some news station and gets mad at Family Guy. She seems more like a political version of Paris Hilton.
