It's really easy.
Hillary Clinton won the popular vote. Hillary Clinton won the popular vote with 65,853,516 (48.5% votes) to Trump's 62,984,825 (46.4% votes) Clinton's margin of victory in the popular vote was larger than John
Kennedy's and Richard Nixon's, I've seen a statistic that her popular
vote margin was the third largest in US elections! (It was the third highest for someone who lost an election, it was also fairly significant among the people who won the election)
Multiple candidates in American history have
been elected president with far smaller margins than Clinton's in the
popular vote. According to figures from
the Atlas of U.S. Presidential Elections—and
as alluded to by one
Atlantic reader—they include:
James Garfield in 1880: 0.09 percentage points
John F. Kennedy in 1960: 0.17 percentage points
Grover Cleveland in 1884: 0.57 percentage points
Richard Nixon in 1968: 0.7 percentage points
James Polk in 1844: 1.45 percentage points
Since the final vote count did, indeed, put her well above 2 percentage
points ahead of Trump, her margin went beyond those of winning
presidential nominees Jimmy Carter in 1976
(2.07 percentage points) and George W. Bush in 2004 (2.47 percentage
points). And all this is not to mention the presidents who’ve been
elected without winning the popular vote at all. That’s a list that
includes Bush in 2000, and Trump.
2,868,686
That is the number of popular votes that Hillary Clinton had over Donald
Trump. It was a number that was 2.1% more of the popular vote than
Donald Trump won.
That is a
number which is larger than the population of 16 States and District of Columbia
(Nevada, New Mexico, Nebraska, West Virginia, Idaho, Hawaii, Maine, New
Hampshire, Rhode Island, Montana Delaware, South Dakota, Alaska,
North Dakota, District of Columbia, Vermont, and Wyoming). It is
slightly less than the populations of 4 States: Mississippi, Arkansas,
Kansas, and Utah). It is slightly more than the combined populations of
Alaska, North Dakota, District of Columbia, Vermont, and Wyoming
(2,578,472).
It's also
a number which is larger than most of the 100 largest US Cities (Only NYC and LA have a larger population).
Now, given that Hillary Clinton won the popular vote by a significant margin: How did Donald Trump become President?
Russian Interference?
The Electoral College?
It was the Electoral College that made Trump President, not any foreign interference.
