I'm tired of hearing about the "popular vote" as well, but for different reasons. People don't vote for the candidate they want... They vote strategically. And the strategy is based on the electoral college vote. If the rules were based on popular vote, people would vote differently and you cannot say what the results would have been. The fact that she "won the popular vote" in an electoral contest is about as useful as a dragster beating a go kart in quarter mile times. Sure it's technically true but that wasn't a metric of victory as they were racing on a go kart course and the dragster did poorly... If they went to a drag strip, the results would be different and maybe the go kart wouldn't have even been in the final matchup.
You can't change the rules of the election without holding another round of voting where people are aware of the rules.
