Here's alternative way to think about this. If you consider the fact that a lot of states are oppressive to their people(minority suppression, anti-choice, anti-environment, etc.) you see that people who can't live under those rules move elsewhere. Often to larger states/cities. The problem with this is that it only sways the electoral college more in the direction of the oppressors. Non-oppressive states get bigger, more inclusive and more open. Oppressive states push a single minded, and often single party, mentality. This essentially locks the power of the electoral college into the hands of the more oppressive states.
