I don't think a Clinton win in Indiana will be a surprise. In fact, it's a must or the contest is over.
I think a Clinton win in NC would be a HUGE surprise though, and would greatly change the narrative.
Anyway, I think that Clinton thinks she can reduce the pledged delegate gap to perhaps 75 by June 3rd and take the popular vote lead. If we then add FL and MI into the mix (and perhaps John Edwards delegates) it becomes a fairly close delegate contest which she could possibly win with a 50 super delegate margin.
