I was disappointed that Nick Clegg's referendum motion was defeated but I feel more mixed about it now.
If you have PR or AV or another variant, you end up with multi party politics, because nobody has overall control of Parliament and regularly shifting coalition governments become the norm.
Germany and the Scandinavian countries manage it well enough (amongst other places). But is that partly cultural? Maybe we wouldn't be very good at cooperative politics. Forming a coalition didn't go so well seven years ago. Maybe we'd get used to it. Maybe it's just not very naturally British.
By extension, it would also mean all successful legislation became more centrist. The radical edges would be knocked if EVERYTHING, so truly innovative law-making becomes difficult. Good for stability, though.
Then there's the business of seeing more representatives from extreme parties in the HoC. How many UKIP MPs would it have been last time? That's the kind of thing FPTP prevents very effectively . And really, what is the POINT in having extreme-wing politicians elected if only very legislation has any hope of making it through?
So based on that understanding, my feelings are a bit mixed. I'm sure you can tell.
