2 party systems are the natural order of things, it seems like. That's just the way the cookie crumbles. It only took one presidential term and one issue (The Whiskey Rebellion/tax protest) to have a 2-party system take a stranglehold on our country. It's the way things work. I agree that that's the case. I'm just saying that the electorate is responsible for this.
You bring up some good points about proportional representation. But that's just another way to define representation. For me, representation means elected officials being directly elected by a plurality of free voters. That's why I've been saying that we still have representation in this literal sense, based on a strong sense of personal responsibility.
