18.3% of the total population of the United States voted for the winner this time. In 2012 it was 20.9%.

Doesn't seem like a huge uprising to me, but those numbers certainly have been disheartening all the same.

All the votes of 2016 election aren't counted yet, so Trump's votes will come up as more than Romney got 2012. Absentee ballots, provisional ballots and early votes are counted later.

Also, the turnout in 2016 election is 2 % higher than 2012 (56.9 % vs. 54.9 %).
