Hillary Clinton: Caucuses aren't elections...but please vote for me anyway!

A few weeks ago, Hillary Clinton argued there was no difference between pledged delegates and superdelegates (which she called automatic delegates). Now she's talking as if pledged delegates don't exist any more -- there's primary delegates and caucus delegates, she says. Huh? What's this all about? Why is she going to Wyoming and saying caucuses aren't elections...and then asking people for their vote? Keith Olbermann and Chuck Todd break it down: it's all part of her undemocratic superdelegate strategy.
