In her lifetime, California Sen. Barbara Boxer has seen her party lose two presidential elections after winning the popular vote -- Al Gore's race against George W. Bush in 2000, and now Hillary Clinton's loss to Donald J. Trump.

A week after her party's White House loss, the retiring U.S. senator has introduced a bill that would amend the Constitution in order to abolish the Electoral College. According to a New York Times estimate, Clinton will be ahead in the popular vote by more than 2 million votes and more than 1.5 percentage points. But Trump got 306 in the Electoral College vote while Clinton got 232 -- 270 is needed to win.

With Republicans now in control of both congressional houses, it's unlikely Boxer's bill will become much more than a political statement. If the long-shot measure makes it through Congress, it would not take effect until three-fourths of the 50 states ratify it within seven years after congressional approval.

In 2012, president-elect Trump voiced his opposition to the Electoral College in a series of tweets -- after it seemed Republican Mitt Romney might lose the electoral vote but win the popular vote. Trump called the electoral system a "disaster for democracy."

He doubled-down on that position during Sunday's 60 Minutes interview, in which he said, "I'm not going to change my mind just because I won." But as of Tuesday, it's unclear whether he would support Boxer's bill.

The same morning Boxer introduced the measure, Trump again took to Twitter to call the electoral system "genius."
