@randahl @bgrinter Annoyingly, the Aussies have thought of part of that, too. Every Australian “electorate” (the seat, or the constituency) is the same population size. So a vote in inner Sydney counts just as much as a vote in the middle of the Northern Territory. Quite neat.
The downside with proportional representation is that if 1% of the population votes for the racists, then the racists get 1% of the seats.
With first past the post, your vote is often wasted, or you are voting for people you don’t really want to win but they’ll get the others out.
All voting systems have their downsides, but I’m quite impressed (as a Brit) at the way the Aussies work it.
