The Electoral College has been one of Democrats' favorite punching bags ever since Donald Trump was elected in 2016, and one of his 2020 opponents thinks she can be the last president ever elected by it.

In a social media video posted Sunday night, 2020 Democratic hopeful Sen. Elizabeth Warren (Mass.) said that it is her goal to get rid of the Electoral College during her first term in office.

"My goal is to get elected, and then to be the last American president elected by the Electoral College," Warren told applauding supporters. "I want the second term to be that I got elected by direct vote," she continued before correcting to "popular vote."

"I just think this is how a democracy should work," the candidate explained. "Call me old-fashioned, but I think the person who gets the most votes should win."

The Electoral College system is designed so that the president is chosen by groups of electors from every state. A state's electoral votes are equal to its number of House members plus its two senators. This is how it balances the concerns of more populous states that get more House members with less populous states whose interests are more strongly represented in the Senate, where representation is fixed. "The Electoral College makes it even harder to win the presidency," Save Our States project director Trent England explained in May. "It requires geographic balance and helps protect Americans who might otherwise have their voices ignored."

This means that a candidate can win the popular vote without winning enough votes in enough states to get a majority of electors, which is what happened to failed candidate Hillary Clinton in 2016 and is the chief cause of Democrats' current desire to end the institution. Prior to that, Al Gore's 2000 loss to George W. Bush spurred calls to switch to a popular vote system.

So, Warren is far from alone in her desire to get rid of the Electoral College, but her proposed timeline for doing so is really questionable. Eliminating the practice of using electors to pick the president would require an amendment to the Constitution, and those don't come easily at all.

Perhaps the most obvious hurdle is that the constitutional amendment process — just like the process of electing a president — also has built-in safeguards to ensure that highly populated states can't run roughshod over the other ones. In essence, to even be proposed, an amendment either needs the support of two-thirds of the Senate or two-thirds of state legislatures, and then it needs three-fourths of the state legislatures' approval for ratification, regardless of how it's proposed. This means that, in order to kill the Electoral College via amendment, a sizable number of representatives from states where voters' interests are better protected by the Electoral College than by the popular vote would have to be convinced to vote against those interests.

And that would be incredibly difficult— if even possible — to pull off, whether the deadline is set at four years or 400.

But constitutional improbability isn't the end of the popular vote discussion. There's also a state-by-state movement to undermine the Electoral College system by assigning electors to whichever candidate wins the national popular vote. Recently, New Mexico became the 14th state to join the National Popular Vote Interstate Compact. In June, Oregon also joined the effort, which brought the total elector count to 196. And while popular among Democrat-leaning states, the interstate movement is also supported by some Republicans such as former RNC Chairman Michael Steele and former Michigan Republican Party Chairman Saul Anuzis.

This story originally indicated that former RNC Chairman Michael Steele and former Michigan GOP Chairman Saul Anuzis supported the federal elimination of the Electoral College. They do not. They support the National Popular Vote Interstate Compact.
