Hillary Clinton’s campaign currently owes vendors $8 million, exclusive of the $5 million she owes herself. She cannot use general election money to pay for this debt. If she begins to be anything less than certain that she will stay in up to the convention, she won’t raise any money and will be stuck with the debt. She also realizes that it is only by projecting an almost manic air of certainty that she has any chance at all of hanging onto super delegates. The first whiff they get of a withdrawal, they will all run screaming to Obama to get on the late train. Don’t think that Hillary is delusional. She knows she’s lost but she has no choice but to play the rest of the game. To fold now would leave her in an untenable situation.
