Helpful, but I can't help but somewhat agree with some of the *shudder* comments there. There's no sensible reason to do your caucuses in such a way, there's barely any accountability, and it just adds layers and layers of easily-manipulated numbers. I'm not saying it should be a straight-up across-the-state head count, but there are literally dozens of statistically useful, intelligent, fair ways of counting votes with changes based on who drops out and where the votes go and such. This isn't exactly one of them.
I'm not too inclined to call foul and say Hillary's campaign really cheated or manipulated things, but more because this one or two coin flips won't make a difference in the grand scheme of things than anything else. For anyone from the outside looking in, the links between Hillary's campaign and the Democratic party vs their dislike of Sanders, coupled with a whole bunch of these systems that are only checked and controlled by the Democratic party with no recourse and no way to verify, really don't make for a pretty picture.
