I have to admit I don't know. I'm away from it many years, and wasn't too interested in electoral systems when I was still there. Here's a wikipedia link:What system do you use in your home country and do you think it is better?

I suppose I could ask as many questions about this.
But I liked the simplicity of the Gemeinderatswahlen in Baden Wuerttemberg, which I was told about by a visitor from Germany recently. She had 40 votes (there were a few hundred candidates), which she could distribute by giving 1, 2 or 3 votes to candidates of choice. I learned today from wikipedia that it's called first-past-the-post, i.e. those with highest amount of votes are elected.
