From the Daily Mail:
Electoral College voters across the country are being harassed by Hillary Clinton supporters, in a last-ditch effort to prevent the Trump presidency.
In the U.S., presidents are elected by the Electoral College - not by popular vote. In most states, electors must cast a vote for the winner of their state's popular vote. But some states - like Arizona, Idaho, Michigan and Georgia - don't have a rule against electors going rogue and voting for another candidate.
So Clinton supporters have been harassing electors in the 21 states with no rules against these so-called 'faithless electors' - urging them not to vote for Trump when they officially cast their ballots on December 19.
In Arizona, electors have been hit with a barrage of emails and phone calls from unhappy citizens - most of them from out of state.
