Dishonest sociopath
i laugh doubly at the idea that they'd do so without seeking almost wholly to attract voters from the three big parties.
Well you don't need to speculate - there is already evidence of the effect of preferential voting in London - where Livingstone attracted more 2nd prefs than Boris by making a pitch to the left (Greens, left LDs, Left List etc.). The fact he didn't win this time was due to other factors meaning he lost on 1st prefs. But the incentives for Livingstone aren't to speak from the centre but to clearly distinguish himself from the Tory position.
Unlike the situation MPs face where the policy is determined purely to target floating voters in middle England. Given that the current situation is already 100% about governing from the centre - the fact that AV allows small parties to get significant 1st preference votes and stake out a clear position can only be beneficial. Yes, it's not the ideal system. But that's not the question here.
On what grounds is it better to keep FPTP that has locked out the left since day one?
