"A president coming in with a significant amount of dissent, this demonstrates to him or her there's some outreach to be done,” Crane said.

Flying across social media Friday, at last count, the petition had nearly 3 million digital signatures.

"Are those real legitimate addresses, is that Mickey Mouse who signed it? We don't know with an online petition how much of that is real or Twitter generated, what have you," Crane said.

For it to work, the petitioners would have to flip nearly 50 Republican electors to get Clinton to that magic number of 270.

Even though Georgia is one of 21 states that allows its electors to go against the state's popular vote, Crane warns that changing those votes is highly unlikely.

"There's not much chance of 50 or more electors, given that they typically are among the party's most loyal members and donors, former RNC and DNC members, that they'll make that switch," Crane said.

In August, Georgia Republican elector Baoky Vu resigned rather than face the prospect of casting a ballot for Trump.

"I fear that the nominee of the top of the ticket, I think doesn't want to win the presidency," Vu said.

While the petitioners' goal might be a wildly long shot, Crane said, "In the political arena, you could make the argument that the Tea Party essentially started that way in opposition to the Affordable Care Act and grew from a bunch of people up in Cobb County, which is where it was actually started, being angry, into a national movement."

In our country's 240-year history, only 157 Electoral College members have ever bucked their party, and nearly half of them did it when the candidate they pledged to vote for died.

The Electoral College votes on Dec.19.
