The changes you’re suggesting would require a constitutional amendment. Ranked choice voting would be a very hard sell in that regard.
If an amendment was ever advanced to eliminate the Electoral College it would be wise to keep it strictly to that and not complicate it.
Why the Democratic Party hasn’t been pushing hard to get rid of the Electoral College is beyond me. Like Gerrymandering, it’s ruined our modern politics, effectively dragging our government to the right of the electorate on most issues.
