The national popular vote is an actual thing, too! Just not a thing that counts, and that’s a problem.
Worth noting that the Constitution does not mandate that states apportion their EV’s according to winner-take-all, and indeed some states don’t.
We could establish a close approximation of a national popular vote if most states abolished winner-take-all; no Constitutional Amendment necessary.
Republicans captured the WH twice in the last 20 years against the popular vote through the Electoral College. For reasons that remain mysterious to me, the Democrats still haven’t made it a high-priority item, but if it happens a third time, I think we’ll see real movements toward reform.
Electoral systems in democracies worthy of the name cannot defy the will of the people forever.
