Unless you are in a purple state you basically don't have a vote, and politicians can ignore your entire State.
So while the EC does empower some rural voters, in reality it effectively disenfranchises most of the country.
That is not a realistic proposal. Political gridlock will never allow a change like this. Doing it state by state is even worse because it just creates a system where dems try to do it to only red states and the GOP tries to do it to only blue states. It would just further skew the outcomes away from a democratic result.
The issue you are having at the state level is a dominant majority makes the views of the minority irrelevant.
And to be clear, the EC does not disenfranchise all the voters in states like CA, just the minority voters.
This is actually precisely what the Senate and the Electoral College is designed to mitigate.
So roughly half of the votes in all non competitive states do not count.
My point is that while the current setup probably dilutes CA liberals voting power the most in terms of the EC, there are other ways the system works that is particularly empowering to CA liberals.
Some people like what California does with its state-specific policies. Some people even choose to live there.
If the Executive branch was less powerful and the States retained more of what they were originally intended to oversee for themselves, I might have less of a problem with California liberals electing the Executive for the whole country.
As it is, California has 53 of 435 seats in Congress and 55 electoral votes. The disparity with Wyoming is just because the minimum is 3 per state, and Wyoming’s population is minuscule.
If you eliminate the per-state minimum I expect there would be large geographical areas of the country which would eventually become uninhabitable / unsustainable.
