Jason notes the fear factor being raised by the Daily Mail against PR. One does have to wonder if the poor dears writing for the Daily Mail in the UK know how PR works. Someone should get Richard Waghorne to help them out with it.
Fact is that the Tories would start life under a new PR system with a much better set up than anyone else. True all 3 of the major UK parties would fracture to some degree in the 1st election under what the form of PR-STV they might adopt, there are the Tories who would vote UKIP as 1st preference but they would come back to the Tories in later counts, the same for the LibDems as the more sandal orientated went for a walk in the meadows with the Greens. But it is the Labour movement which would split the most, producing a jamboree of leftish and far leftish parties that would emerge with so much antipathy between them that transfers would not be forthcoming. The 80s militant era would be a cake walk in comparison. It’s no coincidence that the right has tended to get people elected President in France despite the supposed left leaning nature of their voters.
So come on for the big win Conservatives and support PR. You’ve nothing to lose.
