The DNC rigged the primaries and gave us Hillary as the Democratic front-runner. Many Bernie Sanders voters did not appreciate this. Suffice to say, four million less people (democrats) came in to vote for Hillary than they did in 2008 for Obama: 69.5 million people voted for Obama in 2008. Despite the increase in population and the resulting increase in the number of voters over 8 years, Hillary still only got 66 million this year.
