NEW YORK (CNN) -- With a little less than a month before the election, this week started with a re-examination of Barack Obama's association with William Ayers.

Whether holding a career-launching state Senate campaign event at the home of an unrepentant terrorist should disqualify you from the presidency is up to the people to decide. I tend to see it as a rather low bar to clear if you're going to run the world, but hey, that's just me.

The defense on Ayers from the Obama camp is that they're not friends -- Ayers was "a guy who lives in my neighborhood," as Obama said. This strikes me as a strange argument from the same campaign that ran Spanish-language ads attempting to disparage McCain by highlighting his "Republican friends" like Rush Limbaugh.

Besides the fact that Rush isn't a terrorist and had to be completely taken out of context in the attempt to smear him -- Limbaugh and McCain are best known for their adversarial relationship. Rush has spent the better part of a decade mocking him, most recently on the specific stance that was the focus of the commercial, immigration reform.
