A petition on Change.org calling for the Electoral College to elect Hillary Clinton as President has earned over half of the signatures needed for it to be sent to the governing body.

The petition, launched on Wednesday after Donald Trump was elected President, calls for the Electoral College to “ignore their states’ votes and cast their ballots for Secretary Clinton.”

Although Trump won over the 270 necessary electoral votes to secure the Presidency, Clinton narrowly earned the nation’s popular vote.

The Electoral College – which was first introduced in 1804 – is comprised of 538 electors. Each state’s number of electors is decided by its number of members in Congress, which is dependent on the state’s population. So, when American citizens cast their ballots, they aren’t directly voting for president – they’re voting for electors. This year, Trump took 279, to Clinton’s 228.

Most states use a “winner-take-all” system when it comes to electoral votes, although there is no Constitutional provision or federal law that requires electors to vote a certain way. Twenty-six states and Washington, D.C., do, however, “bind” their electors to vote for the promised candidate on Dec. 19 – in this case, Trump. In many cases, “faithless electors” are forced to pay a fine if they vote against the popular choice.

Maine and Nebraska follow a different method, called the congressional district method, which allots two electoral votes to the popular vote winner, and additional votes for each congressional district won by the candidates.

Faithless electors have not ever reversed the presidency.

The Change.org petition, which was at over 500,000 signatures on Thursday afternoon, said that Clinton supporters would be happy to pay any fees accrued by those who choose to be faithless electors.

“Mr. Trump is unfit to serve,” the petition claimed. “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. Secretary Clinton WON THE POPULAR VOTE and should be President.”

Washington (AFP) - US President-elect Donald Trump visited Congress on Thursday and proclaimed that health care, border security and jobs will be his top three priorities when he moves to the White House next January.

Continuing a Washington victory tour of sorts after his presidential election shocked the world, Trump and Vice president-elect Mike Pence sat down with House Speaker Paul Ryan and then with Senate Majority Leader Mitch McConnell to discuss the Republican priorities in Congress.

Ryan and Trump had a testy relationship during the campaign, with the House speaker last month saying he would not defend the nominee after Trump's lewd comments about women were made public.

Now that Trump is the president-elect, Ryan appeared friendly and gracious as they met, first over lunch and then in his Capitol office.

"We had a very detailed meeting," Trump told reporters at a brief photo spray.

"As you know, health care -- we're going to make it affordable. We are going to do a real job on health care," he said.

Trump made repealing Obamacare, and building a border wall between the United States and Mexico, pillars of his presidential campaign.
