This is definitely one of the better ideas I've read about in Medium about fixing American democracy. From my understanding the US constitution, the states can select their congressmen anyway they want. Maine and Nebraska have already gone different ways.

While USA may be better governed with three or more parties, we really need to get rid of all the political parties. Then we will really move forward.
