Probably a Leftist posing, but... however he leans politically, he's a nutjob and I certainly don't want him identified with conservatism.
Neither do I, but I won’t hold my breath waiting for proof that it either even happened, or that there’s proof that it was from a verfiable conservative. Especially in light of their lack of response to such, and worse, attacks on people like Sarah Palin. She’s gotten a stream of these types of attacks over the years, and they’ve never said one word in her defense. Not one, not even a weasel-worded rejections of the “politics of personal smear”. Not once.
