AV is not perfect. No system captures the will of the people with photographic realism. The goal is a fair approximate, and FPTP fails utterly. It distorts, obstructs, obscures and perverts voter choices. It causes tens of thousands of votes to be wasted; it forces people to endorse candidates they don’t like, just to punish ones they like even less.
AV will not solve all of the problems of British democracy. It will not undo the harm of the expenses scandal, nor provoke a renaissance of civic participation. It is only a reform. It promises one thing: by taking account of multiple preferences, it would elect a parliament that more accurately describes the political complexion of the nation. That is a start.
I am genuinely undecided on which way to vote come the May referendum. There are some strong arguments here though and if I had to give an indication of intention now, I’d probably be veering slightly towards the Yes camp.
