This is idiotic. If you're going to go faithless to undermine the electoral college, and presumably supporting a move to a national popular vote, then electors should throw their support to the winner of the popular vote, Hillary Clinton. An elector pledged to Clinton but casting a vote for someone else (Bernie or whoever) won't stop Trump from getting a majority in the electoral college, or cast any doubt on his legitimacy.
Electors could use their EC vote to make a statement. But to do that in this election Republican electors would have to be the ones to go faithless.
