I think its worth mentioning that winner-take-all elections prevent you from getting your interests represented. So this whole debate is like fiddling with the alignment of your wheels when the car's no longer on the road.
I voted today. A few of the issues I had to vote on had only 1 choice. (I fill-in the bubble, or, not. WTF.) Several had 2 choices, the RP candidate or the DP candidate. A few had 3-5 choices. A few had a blank line for "write in" choice. This is "democracy" in action today in the USA, folks.
We need proportional representation. I'm pretty sure I'd have better choices with PR. Right now its a choice between people that don't understand economics or real life and people that don't understand economics or real life.
