I don't think that negative attacks against Obama are going to be very effective from here on out in the campaign. They may change a few minds, but so many more minds are focused on the economy, and that is clearly Obama's issue. Besides, Obama has so much more money to counteract those ads.
"I don't think they matter hardly at all," Trippi, who worked for John Edwards during the primaries, said of both sides' commercials. "Most people are looking at the financial crisis, looking at their 401(k)s, and in between they're seeing the two candidates beat the living daylights out of each other and rolling their eyes."
Alex Castellanos, the veteran Republican strategist, said Obama's image is hard to tarnish because voters have come to know the senator from Illinois.
"They've seen him for a year and a half in debates," said Castellanos, who worked for Mitt Romney in the primaries. "They've been barraged with television. To come up now and say, 'Don't believe your lying eyes -- this candidate is not who you think he is,' is a very tough challenge."
