What debate was the AP watching?

I hate to nitpick, but considering the issues of substance didn't show up until after about 45 minutes of non-factor fluff, the AP's chronological account seems a little disingenuous (emphasis mine):

Obama later erred by saying he had never favored a ban on handguns even though as a state Senate candidate in 1996 he filled out a questionnaire from an Illinois voter group saying he would support such a ban.

"My writing wasn't on that particular questionnaire ... as I said, I have never favored an all-out ban on handguns," Obama said, even though his handwritten notes did appear on its front page. The reponse to the question about guns was typed.

Obama had more explaining to do moments later, when he was asked about his controversial comment that small town Americans become bitter because of economic adversity, and "cling to guns or religion or antipathy to people who aren't like them" as a result.

Bitter was the first stop on the crazy train at 8:04pm. Gun control didn't come up until after 9:30pm.
