(CNN) – President Barack Obama's heavily criticized debate performance last week was the result of an overabundance of civility, the Democratic incumbent said in a radio interview Wednesday.
"I think it's fair to say I was just too polite, because, you know, it's hard to sometimes just keep on saying and what you're saying isn't true. It gets repetitive," Obama said on the Tom Joyner Morning Show.

Obama's opponent Mitt Romney was widely considered the winner of last week's debate, held in Denver. Many critics, including some Democrats, said Obama appeared unenthusiastic and unwilling to engage Romney on some of the more contentious campaign flashpoints, including Romney's "47%" remark.
Following the debate, the president's allies acknowledged he lost on style points, but argued Romney win was supported by a series of lies about his platform and Obama's policies.
In the interview Wednesday, Obama stuck to that message, saying the tack Romney took last week would wind up hurting the GOP nominee in the end.
"Gov. Romney put forward a whole bunch of stuff that either involved him running away from positions that he had taken, or doubling down on things like Medicare vouchers that are going to hurt him long term," Obama said.
He added that at the next face off with Romney, slated for next week on Long Island and moderated by CNN's Candy Crowley, there would be more aggressive rebuttals to his rivals claims.
"I think it's fair to say that we will see a little more activity at the next one," Obama said.
