John Weaver, the former top political aide for Sen. John McCain, R-Ariz, who left the campaign amidst some acrimony last Summer, tells ABC News that McCain's new ad attacking Sen. Barack Obama, R-Illinois, as a celebrity akin to Britney Spears and Paris Hilton is "childish."
Weaver says that McCain campaign's new strategy of going negative against Obama "reduces McCain. John is capable of inspiring Americans."
Likewise, Weaver said that McCain's attack against Obama for canceling a trip to visit wounded soldiers -- an ad that McCain friend Sen. Chuck Hagel, R-Neb., called "inappropriate" -- is "very not John. It's not the John brand at all."
The new negative McCain, Weaver said, doesn't work. "It's like asking Wilt Chamberlain to play point guard."
Weaver earlier today took issue with the McCain ad in an interview with Marc Ambinder of The Atlantic.
Earlier today, Obama responded to McCain's new ad in Lebanon, Missouri, saying, "You know, I don't pay attention to John McCain's ads, although I do notice he doesn't seem to have anything to say very positive about himself. He seems to only be talking about me. You need to ask John McCain what he's for and not just what he's against."
He also said to a crowd in Rolla, Missouri, per ABC News' Sunlen Miller, "John McCain right now - he's spending an awful lot of time talking about me. You notice that? I haven’t seen an ad yet where he talks about what he’s gonna do."
