@MattGrossmann @mattyglesias Yeah, Bernie *has* been spending some ad $ in early states and the timing's worked out well. We're at a point in the campaign where even an extra 1-2 points in polls (ads probably not worth *more* than that) can move you up a position in IA/NH, which helps with perception, etc. — PolitiTweet.org
