LINK As noted here and elsewhere, the words "William Ayers" appeared nowhere in yesterday's debate, despite the fact that the McCain campaign hinted for days that McCain would go hard at Obama's associations. Now Politico reports that McCain advisers are privately indicating that Ayers, and Obama's pastor, Jeremiah Wright, may be off the table for good: If it's really true that the McCain team is holstering this pistol, it suggests that the McCain campaign's internal polling on how the Ayers stuff is playing is just brutal, likely among independents. It also suggests that Obama's counter-attack -- lambasting McCain's campaign for wanting to change the subject from the economy to personal attacks -- has been effective. Also: No more hits on Ayers or Wright will make for a lot of disappointed conservatives. All that said, whether or not Ayers comes up again, the McCain campaign hasn't stopped with its strategy of painting Obama as a risky and vaguely sinister unknown. The campaign released an ad this morning asking, "who is Barack Obama?," and concluding, "Mr. Obama, we all know the truth."
