In order to secure the nomination at the convention, a candidate must receive at least 2,117 votes from delegates (a simple majority of the 4,233 delegate votes, bearing in mind half-votes from Florida, Michigan, Democrats Abroad and the territories of Guam, American Samoa, and the U.S. Virgin Islands).

In the end, Senator Obama had 1,828 1/2 pledged delegates and Hillary Clinton had 1,726 1/2. It were the Superdelegates who pushed Senator Obama over the 2,117 needed.

Are we now to assume that since he didn't have 2117 pledged delegates in 2008 when he came to the Convention that he's been an illegitimate Democratic president? Because that's what Sanders is selling to his supporters who appear not to know any better.
