History
Understanding the Electoral College in US Presidential Elections
Quick fact
In 2016, Hillary Clinton won the national popular vote by nearly 3 million votes, yet Donald Trump became president because he won the Electoral College 304 to 227. This is the fifth time in US history that a candidate lost the popular vote but won the presidency.
Why this is interesting
You know how every vote should count equally in a democracy? The US presidential election doesn't work that way. In fact, winning the national popular vote can still lose you the presidency.
