Since then we’ve had two elections in twenty years where a candidate who lost the popular vote “won” thanks to the Electoral College. And the Electoral College is still there.
In politics, never underestimate the power of inertia.
I think the bigger point that should be talked about is why everyone has invested so much power in the presidency, and argues that their candidate should have won by a 1% majority and is now entitled to implement their national agenda. That is not the way this country was meant to work. You eventually end up with a dictator.
My best guess at the reason why we do this: tribalism and mass media. Human nature. Gotta have a chief, one person to look to for answers.
When the crisis is over there will definitely be some attempt to roll everything back to the "good old days", but not all of it will stick, and we'll have a different set of trends emerge - and trends in the political system may be among them. But maybe not the Electoral College. I don't see the federal system changing very quickly as a result of any current events.
(Not always in a good way, of course. But still.)
