Theoretically, yes. It’s just highly, highly unlikely.

“There have been a number of occasions in the past where individual electors have, in effect, thrown away their vote,” Jack Rakove, a history and political science professor at Stanford University, told CNN’s Michael Smerconish Saturday.

Since no instance of this in recent history has affected the final outcome of an election, people don’t normally take notice, Rakove said.

But, Rakove said, “If some kind of crisis arose where some group of electors felt that they had to act independently and exercise what they thought was their constitutional authority under Article II of the Constitution, then we’d be in a truly interesting situation.”
