*** Those 18 delegates: Edwards endorsement also did another thing: It undercuts Clintons Florida/Michigan argument. As we know by now, Obama will gain a majority of the pledged delegates after Tuesdays contests in Kentucky and Oregon. But if you award Obama Edwards 18 pledged delegates -- who technically can vote for anyone at the convention, but whom you'd also expect to side with Obama -- then Obama, if he picks up about 50 delegates on Tuesday (less than half of the delegates up for grabs that night), he would obtain a majority of pledged delegates even if you include Florida and Michigan's entire delegations. Here's the math: 4,051 (the DNC convention voting total) minus 797 (superdelegates) equals 3,254 plus FL's (185) and MI's (128) delegates equals 3,567. Divide that by two (and round up), and here's the number needed for a majority: 1,784. Obama currently has 1,599 pledged delegates. Add in those 18 Edwards delegates, add in our low estimate of 50 for him Tuesday and that gets you to 1,667. Now, add in the Clinton best-case scenarios in MI/FL, giving her the delegates with the voting as is, Obama would then reach a majority of the pledged delegates OVERALL. Assume a 105-67 split in FL and a 73-55 split in MI. That gives Obama a grand total of: 1,789.
