DENVER (AP) — Americans heard a lot about the economy and taxes in last night's presidential debate -- but they didn't hear President Barack Obama say anything about the secretly-recorded video in which Mitt Romney tells donors it's not his job to care about the 47 percent of Americans who pay no taxes and see themselves as victims.

An Obama adviser, David Axelrod, is suggesting that Obama didn't mention it because it's already been so widely seen and heard. He tells MSNBC that it's "been very much a part of the discussion."

Democratic ads have been playing up the Romney comment.
