Appearing on a radio show on Wednesday morning US President Barack Obama said he thought he was “too polite” during last week’s debate with Republican presidential nominee Mitt Romney.

I think it’s fair to say I was just too polite," the president said when asked about his first debate performance during an interview on the Tom Joyner radio show. "The good news is, that’s just the first one."

“I think it’s fair to say that we will see a little more activity at the next debate,” Obama said, adding he was not worried about Romney catching up with him in opinion polls after the televised debate.

The US presidential elections are held on November 6.
