Also HC won the popular vote but lost the election.
In 2012, Barack Obama won a majority of votes and became President. In 2016, more Americans voted against HRC than voted for her; and she lost the Presidency with only a plurality of the votes. There were four candidates to choose from for President in 2016, and most polls didn’t bother to report results for third party candidates: with a typical poll size of 1,000 registered voters, the standard predicted error of 3-5% was equal to the total votes for third party candidates.
Meaning if you were a pollster in 2016 and excluded Gary Johnson and Jill Stein from your poll choices, your results for the percentage of votes HRC would receive in the general election would still be within the expected margin of error.
