Both NE and ME should get rid of the split electoral votes, it's bad politics and will tear this country apart if other states try it.
I don't get this. What's so bad about the Maine and Nebraska method? We're already atrociously divided as it is, but why would adopting that method in more states make it worse? The way I see it, adopting that method increases the likelihood that presidential candidates, in the fall election, will campaign in more states. Nebraska would likely never be visited at all by Democrat nominees if the state didn't use the congressional district method. If California were to adopt the district method, then Republican nominees would have a good reason to spend a lot of time campaigning there, instead of writing the whole state off. What arguments outweigh that consideration?
Republicans could implement it in rapidly D trending states like Georgia and Texas, creating a situation where a Democrat could win the state but get a minority of electoral votes from it due to gerrymandering, further biasing the electoral college against Democrats. Democrats wouldn't be able to repeal it until they got a trifecta.
