Bob Schieffer opens the door to bring up Ayers by mentioning Palin’s “he’s palling around with terrorists.”

McCain… notes that he called for town hall debates.

McCain objects to John Lewis said he was associated with “segregation, church bombings… Senator Obama, you didn’t repudiate those remarks.”

Obama charges that “100 percent” of McCain’s ads are negative ads.

McCain: That’s not true.

Obama: It is indeed true.

Obama says, “I don’t mind being attacked for the next three weeks.” (Yes, because after the Fairness Doctrine is reinstated, no one will be allowed to attack him again.)

Obama says John Lewis was unprompted, and was troubled by what he was hearing at your rallies – when my name came up, people were shouting, “terrorist” and “kill him.” Your running mate didn’t say stop, that’s out of line.”

CNN’s line is straight down the middle. The Ohio voters are unimpressed until Obama says, “We don’t think that comparison is inappropriate.”

Obama brings up the “pal around with terrorists” line.

McCain: “I’m proud of the people who come to my rallies. Whenever you get ten thousand twenty thousand people, a few people are going to say some things that are inappropriate.” Cites seeing vets in the crowd.

“There’s some things that have been shouted at your rallies I’m not pleased with, either. Some t-shirts, too.”

Obama says it’s time to get back to the real issues.

McCain mentions Ayers – I don’t care about some washed-up terrorist, but I do care, as it was mentioned in your . One of the greatest frauds in our history, the same outfit your campaign gave $800,000 for.”

Obama charges that Ayers has become the centerpiece of McCain’s campaign.

Obama offers his standard pat answer. I was 8, it was a long time ago. He notes that Ayers worked on a board with Republicans.

Obama says ACORN is a “community organization.” The registry of false names “had nothing to do with us.”
