Not only does the EC recognize state sovereignty, it protects against voter fraud.

No matter how much fraud is perpetrated in the high population cities, they can only affect the number of EVs that their state has, not the entire country.

With regards to the 'popular vote' movement, others could push for a 'counties' movement. The candidate winning the most counties gets the EVs. In most recent elections, the GOP candidates have won more counties, thus more geographical area, nationwide, than the Dems, who tend to win the bigger cities.

You’re close to the idea that I had.

Instead of by county, though, I’d suggest by congressional district, since that’s how 435 of the EVs are apportioned anyway.
