Proportional representation gets discussed a lot here lately 
WRT the situation in the US: I can remember in the late 1980s, when there were elections in the USSR and East Germany, a frequently used expression in the press here to mock the situation was “one-party democracies”. And I remember that I thought to myself: Is the US really that much better, where you can choose between a right-conservative and a right-liberal party (which they were IMHO at least at that time)? If a voter has only two realistic choices, and feels not represented by any of them, it’s no wonder the political system is in decay.
