Likewise some are judging the vote on the systems on the basis of which party(ies) they think it would favour. The truth is we don't know how people would vote with a new system, but clearly parties would need to be mindful of having some appeal to people beyond their core support. If some parties fear AV more than others, that would seem to be a party issue, not a voting system question.
I'm voting 'Yes" because:
- AV eliminates the need for tactical voting. In several recent general elections, people have found themselves voting for a party/candidate they don't want because they want to try and stop the candidate they really don't want from getting in.
- Campaign leaflets often talk about 'wasted' votes for candidates who are deemed likely to be 3rd or 4th. AV eliminates this. You can put your genuine first choice first and then rank the others, according to their relative merits in your eyes.
- Many voters are not neatly defined in one political box. They do have relative preferences. AV enables a consensus to be established as to who is the most acceptable candidate to most of the electorate.
- In a genuine 2 horse race, FPTP works fine. However, in constituencies where 3 (or even 4) parties do quite well, it's possible to be elected by FPTP with 30% or less of the votes. AV helps to sort out who is the best candidate to represent the interests of the majority.
Here's a mathematical take on it all.
