Regardless of your political views, the outcome of the Democratic nomination will create a very interesting situation either way. If Sanders, an older, grumpier, Independent candidate who openly identifies as a socialist, wins the nomination over a well-seasoned, well-known, well-connected, non-socialist candidate such as Clinton, it will easily be considered one of the greatest upsets in our political history. If Clinton wins the nomination, she could potentially be the first presidential nominee to be indicted while running for office.
What made last night's Democratic caucuses so interesting, aside from the fact that Clinton and Sanders virtually tied, was the battle between younger and older voters. If you look at how Iowan Democrats voted by age, it's plain to see that Clinton took home the older vote, while Sanders won huge among millennials.
Ironically, Sanders, Cruz and Trump all make similar arguments: the system is rigged against average Americans; special interests and political "cronies" are reaping the rewards; and nothing short of a massive overhaul is in order. Extreme populism has been on the rise in Europe, and these candidates are attempting to foment a similar sentiment in the U.S.
