Democrats won't initially like this idea any more than they like Greater Idaho, because as mentioned above they are not interested in good government - they desire to rule over the peasants.

State Level Electoral College.
Each county gets 3 votes.
Your guy/gal sweeps with more than 66% they get all 3
50.1 to 65.9…..your guy/gal gets 2 votes, loser gets 1. That way they can’t bitch about it not being overwhelming.
I doubt you’d have a Democrat Governor, Lt Gov, SecState, AG in any but 3 or 4 states.
And no amount of fraud in the cities or Democrat areas could overcome that
