As I wrote back on March 2, I think Clinton will take the battle all the way to the convention. Until the status of the Florida and Michigan delegations is decided and the superdelegates actually vote--and neither event will happen until the convention--she still holds out some miniscule chance of pulling off the nomination. Since she attaches near infinite value to being president and zero value to harming Obama's chances at winning the presidency, she'll stay in until the bitter end. She may even view reducing Obama's odds as a plus, since (she may believe) it sets her up for a run in 2012. Please prove me wrong, Hillary!
