Obama rejects "dream ticket"

Recently the Clinton camp signaled that the former first lady is willing to take up Obama as a running mate.

But Obama beat back any notion of giving up his presidential bid to be Clinton's running mate.

"I want everybody to be absolutely clear. I'm not running for vice president. I'm running for president of the United States of America," he said.

"With all due respect, I have won twice as many states as Senator Clinton. I have won more of the popular vote than Senator Clinton. I have more delegates than Senator Clinton."

The Illinois senator went on to say, "It's like when somebody’s trying to bamboozle you. When they're trying to hoodwink you. They are trying to hoodwink you."

Party elders to step in

Worrying about the prolonged internal fight, Democratic Party elders said they are prepared to step in.

Democratic Party chairman Howard Dean said he's willing to step in to avert any outbreak of internal conflicts at the August 25-28 convention in Denver.

"If we have to sit the two candidates down together, or their campaigns down together, and try to figure out how to make peace and have a convention that's going to work, then that's fine," Dean told ABC News.

"That is my job, and we'll be happy to do it," he said.

However, Dean said it's still too soon for that meeting, with more state primaries to come.
