Ben Keeler, at politics.ohio.com, posits the likely routes that the Clinton presidential campaign will follow.  For me, there is no option other than C: 

"She stays in through the end of the voting calendar and sees what happens, hoping for a huge Obama stumble. Two good states for her coming up which she will win and keep fighting for Florida and Michigan to count. I still think this is the most likely of my three options to occur. Team Clinton does not seem to have given up on the two problem states. I do think, however, that talk of blowing up the convention is overblown. I can't envision that happening."

As I mentioned yesterday and before, the Clintons are never to be underestimated.  They are the cockroaches of American politics.  I hate horserace politics but the Clintons are so good at it that it almost defies belief.  If they are in it, they have credibility.
