MIAMI, FL - As if on cue from Steve's post, the Hillary Clinton campaign has scheduled a conference call at 1pm eastern to announce a "major" endorsement. Any guesses who it might be? UPDATE: Halperin says it's Maxine Waters, which is not terribly "major," in my opinion, but potentially helpful in a delegate rich state.

Incidentally, the Clinton campaign has also scheduled a 12:00pm call with Campaign Manger Patti Solis Doyle and Chief Strategist Mark Penn to discuss "the importance of Florida." You don't say.
