Quick read....
This gets rid of the threat (as was tried in 2016) to have "faithless electors" vote for whoever they wanted to rather than that states popular vote winner.
This just ensures that the electoral college does not disconnect from the citizen voters and become their own backroom deal making cabal.
What needs to be decided is if a state can legislatively disconnect its voting citizens from their STATE vote results and force Electors to vote for the winner of the NATIONAL popular vote.
Some state have done this legislatively already.
Basically they have told their citizens "We dont give a shit what you want in Wyoming. You are going to get what New York, Chicago, and Houston want you to get!" (Wyoming only used as an example....I dont think they adopted the legislation - but I know a few states have.)
This last is a travesty of the Constitution and needs to be struck down. Ditto "Rank Choice Voting".
We do not operate on "Majority Rule" in this Republic.
