I don't see the EC going away anytime soon, however, I think this is one of the more reasoned arguments for changing how it is currently implemented:
There’s now another suit, filed in Colorado this week, where two Democratic electors are trying to undo the Colorado law that demands that all nine electors vote for the winner of the state’s popular vote (Hillary Clinton in this instance). They seek to be freed up to vote for someone of their choosing, neither Clinton nor Trump. As they put it: “Plaintiffs may vote for a consensus candidate, other than Clinton or Trump, upon whom electors from both parties and along the ideological spectrum can agree, so as to prevent the unqualified Mr. Trump and Mr. Pence from ascending to the highest offices in the United States.” These electors aren’t relying on the Equal Protection argument, but rather on the idea that the whole purpose of the Electoral College was to allow electors to vote as they saw fit, and state laws forcing them to support a candidate renders the whole idea of electors “superfluous.” The Colorado plaintiffs claim that the Constitution intends for the Electoral College to “be a deliberative and independent body free to cast votes for whomever they deem to be the most fit and qualified candidates.” These plaintiffs allege that “nominees for President and Vice-President, Donald Trump and Mike Pence, represent a unique danger to the Republic and embody the very reason why the Founders created the Electoral College.”
