Hillary's close call in Indiana means she is just barely alive. She certainly didn't win the expectations game this time around. This, of course, begs the question: Is it over, yet?
I think there's about a 30 percent chance she will get out of the race this week.
A more likely option is that she will mount a pro-forma campaign -- win West Virginia and Kentucky -- and then get out on a positive note. This scenario may help cement her status as the presumptive nominee next time around (depending on how things pan out in the general election).
The idea that she will mount a serious attempt to "steal" the election from Obama, via superdelegates, is sadly becoming less and less realistic.
