CBS News and AP with :video (02:29)from The Early Show
Democratic Party chief Howard Dean said in an interview with CBS News' The Early Show that he wants all Democratic superdelegates to make their choice before July 1 to avoid a contested convention.Howie P.S.: Bob Casey endorsed Obama and Pat Leahy asked Hillary Clinton to abandon her White House run today.
Dean also said the Michigan and Florida delegates will be seated at the convention. But he won't force a resolution because he said there's nothing the Obama and Clinton campaigns can support at this point.
"You bring both sides together and say, `Don't you think it's time that the two campaigns made a deal on how we're going to do this?"' Dean said. "Let me just say that the campaigns believe that kind of a deal is premature right now."
