Mary Cheney, 24/7
It didn't enter the lexicon of political scumbaggery in 2004, but it should have. Like Swiftboating, Mary Cheneying is shorthand for a deliberately dishonest political tactic. To Mary Cheney, one feigns umbrage at an innocuous, legitimate and truthful comment order to falsely accuse one's opponent of a personal attack or invasion of privacy. Various hacks in the media (see Kurtz, Howie) repeat the Mary Cheney, as do various pinheads with their own blogs, thus turning the Cheney into a "legitimate" news story. Two of the biggest stories stinking up wingnut blogs and glorified blogs such as Politico.com at the moment involve the McCain campaign Mary Cheneying Senators Obama and Biden.
Such scumbaggery will increase exponentially as we draw nearer to the election.
