Observation, Thought, Question, and Theory

Observation: More than likely, Clinton still doesn't have a route to the nomination through voting along any of the mathematical measures.

Thought: Hillary Clinton doesn't just need a better argument, she needs an overwhelming argument because she is asking the superdelegates to overturn the nominee selected by the voters and take the less defensible position before their constituents.

Question: Who will the superdelegates blame as all the public pressure comes crashing down on them and their electoral chances are affected?

Theory: The superdelegates facing reelection will want this over soon and will try to influence it without getting caught on the public record.

(PS. It's not at all unrealistic that Obama will recover any Clinton gains tonight in North Carolina alone.)
