From the Wolf Blitzer Reports staff in Washington:
WASHINGTON (CNN) -- Throughout much of the primary campaign, there was speculation about a Kerry-Edwards ticket. John Edwards said he wasn't interested.
"I am only interested in being president of the United States," Edwards told CNN before he dropped out of the race.
But that was then, and this is now.
"John Kerry has what it takes right here to be president of the United States, and I, for one, intend to do everything in my power to make him the next president of the United States," Edwards said Wednesday as he announced he was no longer in the running.
Even if Edwards is willing to join the ticket, he's just one of many potential vice presidential candidates, including some other drop-outs from the Democratic presidential race, including retired Gen. Wesley Clark, Missouri Congressman Dick Gephardt, and retiring Sen. Bob Graham of Florida.
Potential V.P. candidates also include Florida's other senator, Bill Nelson.
"I think I'd consider such an offer were it to be made," Nelson told CNN's Wolf Blitzer on Wednesday.
There's also talk about another member of the U.S. Senate, former first lady Hillary Clinton.
In an interview with CNN Wednesday the junior senator from New York said, "I don't think I would ever be offered. I don't think I would accept."
One former governor and current senator is being mentioned is Indiana's Evan Bayh.
Asked what he'd do if offered the number two spot on the ticket, Bayh responded, "Oh, I don't think you say no to that kind of thing."
Then there are these current Democratic governors: Iowa's Tom Vilsack, Virginia's Mark Warner and New Mexico's Bill Richardson.
Gov. Richardson says of being the vice presidential nominee, "It's not an option. So I'm staying where I am."
Arizona Gov. Janet Napolitano and Pennsylvania Gov. Ed Rendell also are among the names being floated.
