U.S. President Barack Obama and Republican challenger Mitt Romney are stepping up their appeals to voters in battleground states that could be key in determining the outcome of the November election.

Mr. Obama reached out to women voters Friday during a appearance in Virginia. He said Mr. Romney could “turn back the clock” for women on issues such as abortion and equal treatment in the workplace.

Mr. Romney and his running mate, Paul Ryan, are set to campaign in Florida later Friday.

On Thursday, Mr. Romney shared the stage with Mr. Obama at a New York fund raising dinner hosted by the Catholic Archdiocese.

In light-hearted comments, the former Massachusetts governor poked fun at the media, which many Republicans accuse of favoring Democrats.

“Let's just say some in the media have a certain way of looking at things. When I suddenly pulled ahead in some of the major polls, what was the headline? 'Polls show Obama leading from behind.' And I have already seen early reports from tonight's dinner. Headline: 'Obama embraced by Catholics,' ' Romney dines with rich people.'”

Mr. Obama made light of his performance in the first debate, during which many said he looked tired and uninterested.

“This is the third time that Governor Romney and I have met recently. As some of you may have noticed, I had a lot more energy in our second debate. I felt really well rested after the nice long nap I had in the first debate.”

Recent polls show both candidates locked in a tight race, with less than three weeks remaining before the election.

Both men are gearing up for their third and final debate on Monday. The showdown, in Florida, will focus on foreign policy.
