I don't find UKIP particularly palatable, but I'd rather we had a proportional system, which would very likely require rather more consensus on a lot of matters - there are quite a few areas where the stated policy of the fish people is not in line with the Cons, after all.
I also tend to the view that you may as well give people rope, and see what they do with it. So what if we have UKIP MPs? If they turn out to be the same quality as the people they send to Brussels, they will be spectacularly ineffective, and very likely a one parliament wonder. They could surprise us and turn out to be diligent constituency representatives - in which case, if people vote for them, what's the problem?
@arrbee:
I think even more than the case of the SDLP, this election has highlighted the problems in the current system, not least because there are more extra parties. But also in the way the election is fought in a tiny number of marginals.
The Labour vote share was, in fact, up by 1.4% over 2010, yet they still lost 27 seats.
The Conservative vote was up by half that, 0.7%, and they gained an extra 24.
In essence, the Labour votes were in the 'wrong' place (as were those of others), while the Tories did better and targeting the seats they needed to win.
In my local seat (Hackney North), the Labour share was up 7% at 62%; also remarkable was that the Greens went up to 14.6%, just 0.1% behind Con. But those increases for the two left of centre parties made no difference.
PR has been something that, certainly, SDLP/LD types have wanted for ages, but I think the raised profile of three extra parties this time round - SNP, Green, UKIP - has opened the eyes of many more people to the flaws in our system.
