John Weaver, longtime McCain loyalist, calls his latest raft of nasty ads “childish.” [Update: another Republican strategist calls it "juvenile."]
Meantime, here’s what looks to me like a very strong Obama response, which quickly segues from calling McCain a liar (using five short quotes from authoritative sources, the phrase “politics of the past,” and the word “old”) to laying out the Obama sound-bites.
One thing we don’t have to worry about this year is having the Democratic candidate let himself be used as a punching bag. They breed ‘em tough in Chicago.
