Nicheuk: Clegg's price for coalition was a referendum on PR. The problem was that the question wasnt 'do you want PR' it was 'do you want a particular style of PR'?
Even Clegg, its biggest supporter had to admit that the type chosen was probably the worst one available.
The irony now of course is that the Naysayers like Slacker will tell you that PR leads to coalition governments and after the last 5 years coalition governments are a bad thing (of course if the coalition had been lib/lab we wouldn't have heard a thing)
What a proper PR system would mean is that a tory voter in Bolsover or a labour supporter in Chelsea would have a vote that would actually mean something. Might lead to greater engagement of the people in politics and far less protest voting.
Fly: not sure why it has to be that way. The public are already disillusioned with politics. Faced with 'more of the same' thats unlikely to improve
