A change.org petition that calls on members of the Electoral College to cast their votes for Democrat Hillary Clinton instead of Republican Donald Trump had more than 1.3 million signatures by late Thursday.

Clinton won the popular vote in Tuesday’s presidential election, 60,269,080 votes to 59,930,946 for Trump. The peculiarities of the Electoral College, however, gave Trump the victory, 290 electoral votes to Clinton’s 228, making Trump the fifth minority president in U.S. history.

Lady Gaga urged her supporters to sign the petition, noting “half the population” is in fear a Trump presidency will mean a loss of rights.

Members of the Electoral College meet in their state capitals Dec. 19 to vote for president and vice president. Forty-eight of the 50 states award their electoral votes on a winner-take-all basis, while Maine and Nebraska award theirs by congressional district with the votes representing the states’ two senators going to the top vote-getter.

“We are calling on the electors to ignore their states' votes and cast their ballots for Secretary Clinton. Why?” the petition reads.

“Mr. Trump is unfit to serve. His scapegoating of so many Americans, and his impulsivity, bullying, lying, admitted history of sexual assault and utter lack of experience make him a danger to the Republic.”

The petition says even in the 24 states where changing the vote is not allowed, a vote for Clinton “would still be counted,” with the elector required to pay a small fine, “which we can be sure Clinton supporters will be glad to pay!”

Demonstrators took to the streets across the United States Wednesday and Thursday to protest Trump’s win. In Los Angeles the protesters burned the president-elect in effigy. In Las Vegas, Chicago and New York, demonstrators gathered at Trump towers to chant, “He’s not my president.”

The rancor follows a divisive campaign in which much of Trump’s rhetoric vilified minority groups, immigrants and women.

In claiming victory early Wednesday, Trump promised to be a president for all Americans in his first attempt to heal the divisions.
