As for the scandal of the electoral college bring victory to candidates with fewer votes, as in 2000 and 2016, there could be an effective reform on the way.

I refer to the national popular vote interstate compact

It's an agreement that the states concerned commit themselves to throwing all their electoral votes to whichever presidential candidate gets the majority of popular votes nationally - but that only comes into force once enough states have signed up to ensure 270 votes.   And at present enough states have signed up to bring that into reach (mostly states which tend to vote Democrat, but not all.)

If all the states that voted for Biden this time were signed up to the compact, they'd have reached that 270. It wouldn't make any difference what any states that hadn't signed up did, the person who won most votes would still be president every time.

Of course it would tend to make the TV coverage of election night a lot less entertaining, but also rather less painful.
