I?m minded to adopt AV, for one main reason Given the downward trend in voter turnout over the last several decades, the introduction of A New System (I?m agnostic about which one ? but AV stands the best chance of adoption. It, like any system, has it?s pros and cons so given that fact?. ) it?s a once in a generation chance to press the reset-button with the electorate and say ?ok you have expressed your antipathy to the current system ? here is a new one which you will need to sit down and engage with but gives you a chance to influence the outcome in a way you couldn?t before? You can argue that the response might still be ?don?t really care mate? but I suspect we would see a significant increase in turnout, for at least the first couple of elections. And as a democracy, I don?t think the current levels of participation are sustainable so I can only see the chance to increase turnout as a good thing
