Several prominent Clinton supporters are now pushing for Obama to select Clinton as his running mate. But former President Jimmy Carter has publicly warned against what some Democrats are calling the dream ticket.

Jimmy Carter: “I think it would be the worst mistake that could be made. I’m on the outside; I’m not involved in the internal affairs of the Democratic Party at all. But I think that would just accumulate the negative aspects of both candidates.”

On Wednesday, Obama named former President John F. Kennedy’s daughter, Caroline Kennedy, to be part of a three-person team to lead his vice president search committee. Obama also named Deputy Attorney General Eric Holder and longtime Washington insider Jim Johnson to the committee.
