FWIW, if I got a call about the dem candidates, I'd choose Sanders. DUHHH!
Rather then go into hysterics because their candidate of choice is not on top, the campaign bots around here might what to consider that is actually an impetus to their campaigns to work harder in these states.
Scoring in the polls is one thing, actually getting voters to the polls is a completely different kettle of fish. One of the worst thing that can happen to a campaign is they start coasting because of the good polling.
