In the
2016 United States presidential election, ten members of the
Electoral College voted or attempted to vote for a candidate different from the ones to whom they were pledged.
[1] Three of these votes were invalidated under the
faithless elector laws of their respective states, and the elector either subsequently voted for the pledged candidate or was replaced by someone who did.
[2][3][4] Although there had been a combined total of
155 instances of individual electors voting faithlessly prior to 2016 in over two centuries of previous US presidential elections, 2016 was the first election in over a hundred years in which multiple electors worked to alter the result of the election.
