I suspect that AV will tend towards centerist middle of the road politics. Which may or may not be a bad thing. I recall a quote from the film the Third Man "in Italy for 30 years under the Borgias they had warfare, terror, murder, and bloodshed, but they produced Michelangelo, Leonardo da Vinci, and the Renaissance. In Switzerland they had brotherly love - they had 500 years of democracy and peace, and what did that produce? The cuckoo clock" Okay the Swiss didn't actually invent the cockoo clock, but you pays your money and you takes your choice.

Personally its FPTP for the me. I prefer a bit of edge to my politics
