Even though neither candidate has agreed to a so-called dream team ticket, they might not have a choice if the unaligned superdelegates make a dual ticket a condition of their endorsement of Obama, Newsday reported Friday.

"If Sen. Obama is the nominee, it will be a very serious option that he has to give serious consideration to," says Simon Rosenberg, a longtime Democratic Party operative in Washington. "She's won a lot of delegates, she's raised a lot of money, she would bring a lot to the ticket."

Among those pushing for a dream team ticket is former Rep. Harold Ford, D-Tenn., head of the centrist Democratic Leadership Council, and former Clinton staffer Sam Arora.

But critics say a duel ticket would be bad for Democrats.

"It's think it's a nightmare," said Andrew Polsky, a political science professor at Hunter College. "There's a long list of her comments (by Clinton) that could be trotted out that would make it a very uncomfortable fit for her to be on the ticket."
