With Clinton + Edwards coming within four delegates of Obama, the possibility of a convention fight looms. In order to avoid fights at the credentials committee, rules committee, or floor of the convention, it is important for Obama to secure the as many of the 28 remaining uncommitted delegates from Michigan as possible, and to improve on the delegate projections for states and territories yet to hold nominating contests. It is also important that the remaining superdelegates commit to a candidate, just as almost every primary voter or caucus goer has already had to commit to a candidate. I still don't see a way for Clinton to pass Obama, short of Edwards moving his delegates to her in a block. Remarkable that Edwards still has an important role to play in the campaign, even at this late date.
