"In the United States Electoral College, a faithless elector is an elector who does not vote for the candidates for U.S. President and U.S. Vice President for whom the elector had pledged to vote, and instead votes for another person for one or both offices or abstains from voting." https://en.wikipedia.org/wiki/Faithless_elector
@spiderduckpig Quite a few states passed laws that invalidate faithless electors after 2016. And that's in addition to the fact that the general mood among Democrats this election is very different to 2016, the loss is much less of a surprise and isn't paired with a popular vote victory, among many other things.
