NEW YORK - Barack Obama isn't interested in running for vice-president of the United States and the Democratic presidential hopeful made that clear during an appearance Monday on CBS's "Late Show with David Letterman."
Letterman asked Obama if there had been any discussion of the Illinois senator sharing the Democratic ticket with New York Senator Hillary Rodham Clinton.
"No, you don't run for second," Obama said.
"I don't believe in that."
Obama also told Letterman his family is holding up well on the campaign trail.
"I take my kids occasionally," the candidate said.
"Malia, who's eight, Sasha, who's five, we take them on the campaign trail and they see these big crowds."
"I ask them sometimes: 'How's it going?' and the last time I did that, my eight-year old turned to me and said: 'This is terrific, daddy, but what are we doing here again?"'
"She wasn't overly impressed."
Still, Obama said he's not going back to Chicago very often.
"My wife is starting to refer to me as her first husband," he said.
"It's a little disturbing."
