I don’t see how STV is confusing for voters: you just rank the candidates in order of how much you like/hate them…
But the main issue is if we try to get STV, we’ll more likely end up losing MMP entirely as people will vote for FPP in a referendumb…

True, i didn’t realise it was that long ago, maybe people’s perception of STV might have changed since then…
