I wouldn't think they'd want to roll out an important endorsement the day before he's SURE to get blown out. That will make Edwards look irrelevant. Wednesday makes more sense, like the loss doesn't affect his ability to win endorsements, but I very seriously doubt Edwards will endorse at all until Obama is the nominee, since he and Elizabeth can't agree. I see them waiting out the primary, then campaigning like crazy for Obama in the general.

"in the event this thing does unravel and go to the convention"

That is straight up BS, that isn't leadership, that is opportunistic and pathetic all at the same time.
