mccain linked to ayers

This, as Andrew Sullivan points out, is Obama's best defence on Ayers if McCain does raise it in the debate:

Republican machers Walter and Leonora Annenberg gave the former terrorist $50 million. They also gave money to Rick Santorum, Strom Thurmond and Mitt Romney. Annenberg was Nixon's ambassador to Britain. If Obama is "palling around with terrorists," the Republican Annenbergs are funding them. Yesterday, the McCain campaign put out a press release boasting that Leonore Annenberg had just endorsed him for president.

It seems crazy to publicise an endorsement from the major funder of the guy you're trying to turn into a bogeyman. I think that's because it is crazy.
