The prospect of the nomination not being locked up before the start of August's Democratic National Convention in Denver is making the rounds in political circles. Here's one bit of punditry from ABC's The Note:

 "Barack Obama's advisers are anticipating the possibility of a Democratic presidential race deadlocked past the last primary, and the outcome may hinge on a fight over whether delegations from Florida and Michigan get seats at the party's national convention in Denver," Bloomberg's Catherine Dodge and Alex Tanzi write. Among those fearing the prospect of a brokered convention: DNC Chairman Howard Dean. "I think we will have a nominee sometime in the middle of March or April," Dean said in an interview on New York 1, per the New York Sun. "But if we don't, then we're going to have to get the candidates together and make some kind of an arrangement. Because I don't think we can afford to have a brokered convention -- that would not be good news for either party." (Would a pre-brokered convention be that much better? And who's got the juice to force either Obama or Clinton out of the race? Try finding a party elder who doesn't have a horse.)
