I am sorry every state changing their border every census would be insane as proposed in the bullet points. States are more than voting bodies. They have their own laws and locally governed territory with shared jurisdiction on some things with the federal government.

Secondly, there is nothing wrong with electoral college it's working as intended. It's like a lot people forget we have states for reason. For instance a lot of the small states with a low population contain the vast majority of federal land. So any federal policy regarding that land effects them more than anyone else. How do think Nevada would react if the federal government decided to start nuclear testing again and their say in politics is reduced even more.

A lot of this I think boils down how you view the US. Are you citizen/resident of your state which is a member of the united states or are you are citizen of the unites states that happens to reside in a state? (A better/clearer way to phrase this would be appreciated)
