Wait, aren't there some delegates that have/will end up being unallocated for one reason or another (or am I thinking of the delegates that are "unallocated" because they're superdelegates)? If it were really close and there were a handful of pledged delegates that were for whatever reason unallocated, then it might make sense. However, that scenario seems rare (and especially if there aren't any unpledged delegates that are unallocated). I'm pretty sure based on the tone of the article - despite the contradictory part at the end of the quote - that it is referring to "a majority of pledged delegates"...so this scenario is the only one in which I could see that happening.
I don't think the Democratic Party has any "unallocated delegates", other than the super-delegates. Unless a candidate wins delegates and then drops out, or "uncommitted" wins delegates, but neither have happened so far.
