The prospect frightens a lot of people because they see it as empowering extremists. But what a proportional representation system does is make the elected representatives more exactly represent the range of political views of the voters -- and a lot of people are centrists.
So, here's a possible scenario: We introduce proportional representation, which causes the two-party system to break down, and ultimately sort itself out into a (more or less) three-party system: The Commie Pinko Lefty Hippie Tree-Hugging Pot-Puffing Moonbat Party; and the Pig-Ignorant Troglodyte Bigoted Greedhead Right-Wingnut Party; and the Wishy-Washy Squishy-Spined Centrist Moderate Mugwump Party. (And, those will the the official names.)
In that system, the Mugwumps (formed out of the centrist remnants of the present Dems and Pubs) rule. Because the Wingnuts and the Moonbats can never agree on anything, no bill can ever pass Congress without the Mugwump vote. It would be stabilizing, while allowing everybody across the spectrum to get a fair say in the highest halls of power.
