Propotional representation is not with out its problems, but I think given that our current system has a bicameral legislature where one body (the Senate) basically just represents entrenched power interests and is badly divorced from the will of the people, and grossly unrepresentative (since it's 2 per state where states have differing populations), I think we could gain a lot by making that body proportional.

Would it be perfect? Nah. Would it be -a lot- better than what we have? Yes.

With the Senate proportional party, and the House still geographically representative, and then if you add in ranked choice voting, you could break the two party system and have a much, much more representative government.

This the easiest and most realistic step in my opinion; the people lobbying heavily to preserve the current Senate system would just be entrenched local tyrants. I think the vast bulk of Americans would be swayed by the idea of having at least one Senator who almost completely shares their politics.

If the result is that the Senate becomes the most interesting and representative body, gradually shift the bulk of power there on whatever issues it's best at. If the result is that the Senate becomes a disaster, abolish the entire body.
