Reversing course, President Trump came to the defense of the Electoral College after recent comments made by Democratic 2020 contenders questioning the voting system.

“Campaigning for the Popular Vote is much easier & different than campaigning for the Electoral College. It’s like training for the 100 yard dash vs. a marathon. The brilliance of the Electoral College is that you must go to many States to win. With the Popular Vote, you go to…

"....just the large States - the Cities would end up running the Country. Smaller States & the entire Midwest would end up losing all power - & we can’t let that happen. I used to like the idea of the Popular Vote, but now realize the Electoral College is far better for the U.S.A.”

The Electoral College apportions its 538 votes by state. Popular votes in states generally determine which candidate gets the vote of all the state's electors, making it possible for a candidate to win the electoral vote without winning the popular vote. A candidate must get at least 270 votes to win the presidency.

Sen. Elizabeth Warren, D-Mass., called for an end to the Electoral College system Monday during a town hall event, saying, "My view is that every vote matters. And the way we can make that happen is that we can have national voting, and that means get rid of the Electoral College."

Warren isn't the only 2020 candidate to advocate ending the method. Former Rep. Beto O’Rourke said Tuesday that he sees “a lot of wisdom” in abandoning the system.

Trump tweeted his criticism of the Electoral College after the 2012 presidential election, calling it “a disaster for a democracy.” Trump lost the popular vote in the 2016 presidential election but won the Electoral College.
