Only 5 US Presidents have ever lost the popular vote.

1824 - John Quincy Adams (lost by a margin of 38,221 votes)
1888 - Benjamin Harrson (lost by a margin of 94,530 votes)
1876 - Rutherford B. Hayes (lost by a margin of 252,666 votes)
2000 - George W. Bush (lost by a margin of 543,816 votes
2016 - Donald J. Trump (lost by a margin of 2,864,974 votes)

The Donald is by far the biggest loser in US history, however.

In fact, he's more than 5 times the loser that Dubya was !

Betcha that he also resigns the Presidency before he can be impeached just like Tricky Dick did in 1974.
