Slate's Dickerson:

Clinton is pleading for time, arguing that voters should be allowed to have their say in future contests. But even in this she comes up against a contradiction posted by Obama's lead. Because she must rely on the superdelegates to beat back Obama's likely lead in the popular vote and among pledged delegates, she is essentially asking those superdelegates to listen to the people—but only long enough to be persauded to vote for her. Then she expects them to undo the will of the people by voting against Obama in Denver.
