DENVER, the United States, Oct. 3 (Xinhua) -- U.S. President Barack Obama and his Republican challenger Mitt Romney on Wednesday began their first presidential debate at Denver University in Denver, Colorado, with the debate focusing on economy and domestic issues.
Economy is the most important topic, as it takes up half of the time.
Prior to the debate, both campaigns had said it would give the candidates an opportunity to speak directly to voters without the filter of the media.
The debate has higher stakes for Romney, as he is trailing the president in polls. Ben Ginsberg, a top Romney campaign aide, said Wednesday morning at a Denver briefing that the former Massachusetts governor will try to showcase his contrast with Obama in their visions for America for the next four years.
There is some unfavorable buzz against the Obama campaign heading into the debate. Vice President Joe Biden, a top Obama surrogate, said Tuesday that the middle class had been "buried" during the past four years, a statement that Republicans immediately seized upon as an unwitting indictment of the Obama presidency.
