Hillary Clinton's popular vote lead keeps growing, even as President-elect Donald Trump scrambles to put together his administration. As of Wednesday morning, the former secretary of state had registered some 2 million more total votes than Trump, according to a Cook Political Report analysis.

The Democratic presidential nominee had totaled 64,223,958 votes, compared to Republican Trump's 62,206,395. That's a margin of 2,017,563 votes, up about a quarter of a million votes from just the day prior. Overall, Clinton has won 48.1 of the popular vote, compared to 46.6 percent for Trump.

Clinton, of course, lost the election based on the results of the Electoral College. Trump won key swing states such as Florida, Wisconsin, Pennsylvania and Ohio to earn 290 electoral votes, outpacing Clinton at 232.

But the fact that Clinton lost despite garnering far more votes than Trump has left a bitter taste in the mouth of some. California Sen. Barbara Boxer, a Democratic Clinton supporter, has put forth legislation to get rid of the Electoral College.

"Hillary Clinton now leads by more than 2 million votes," Boxer tweeted Wednesday. "It's long past time to end the outdated Electoral College!"

It's very unlikely, however, that her legislation will pass through the Congress currently controlled by the GOP.

Trump himself has waffled about views on the Electoral College. When then-Republican presidential nominee Mitt Romney briefly led the popular vote in 2012 despite being on track for a loss, Trump called the Electoral College "a disaster for a democracy." After Trump won in 2016, however, he called it "actually genius," then reversed course again in a Tuesday meeting with the New York Times, reportedly saying he would "rather do the popular vote."

Clinton's popular vote lead has continued to expand largely due to an influx of absentee and provisional ballots in California, a Democratic stronghold, USA Today reported. She led by 3.74 million votes in the state as of Wednesday. But in the cumulative vote in 13 key swing states, Clinton trailed by more than 850,000 votes.
