Donald Trump owes his victory in the Electoral College to three states he won by the smallest number of votes: Pennsylvania, Wisconsin, and Michigan. So it's fair to say that the 2016 presidential election was decided by about 100,000 votes out of than 120 million ballots cast. According to the latest tallies, Trump won Pennsylvania by 1.1 percentage points (68,236 votes), Wisconsin by 0.9 points (27,257 votes), Michigan by 0.2 points (11,837 votes). If Clinton had won all three states, she would have won the Electoral College 278 to 260. She fell short in all three, of course, and that's why we are now getting accustomed to the reality of President-elect Donald J. Trump.
