Personally I'd rather 'pretending' played no part in an electoral system
So let's stop pretending that there are only two political parties and that nobody else's opinions count if they don't vote for one of the top two in their particular area.
That is why we currently get hundreds of leaflets telling us 'its a two horse race' and 'only xxx can beat xxx here', often with competing parties telling us they they are both in second place in the same race based on different elections or their own surveys. At present if you don't vote for one of the two top parties, your vote is wasted. Too many people pretend to support one of the top two parties because that is their only real choice if they wish their vote to count, even if it is really their 8th or 9th preference in reality. The current system simply hides the preferences of many voters.
AV puts an end to wasted votes and tactical voting. It is fair and transparent.
