Well, Paris Hilton has finally responded to the ad in which John McCain’s campaign compared her to Barack Obama. Turns out that now she’s throwing her hat in the ring — and that she’s got a pretty interesting energy policy. I don’t know why everyone’s so surprised; if you’ve seen her star turn in “House of Wax,” you’ll know the kind of intelligence she’s capable of. The only question I have now is whether Britney Spears supports cap-and-trade.
