While the coalition governments that arise in a proportional representation setting have their own sets of problems, a fairly significant number of studies have shown that PR systems increase both voter turnout and voter satisfaction. I often see people deriding the two party system in the US, but rarely any mention of different ways of doing elections. It's certainly not unprecedented for a country to switch from a first past the post system to a PR system. Additionally, the US House of Representatives seems particularly well suited for elections by proportional representation.
