crazymoloch has a good post on what the magic number for the Democratic nomination should be.
His conclusion?
Either 1,614 -- which would guarantee a plurality of pledge delegates (assuming Florida and Michigan are not seated) or 1,771 -- which would guarantee a plurality of pledged if FL and MI are seated.
The formal magic number is 2,025, which includes super delegates, but I cannot imagine that the super delegates would go against the popular vote.
