So Danny Finkelstein’s blog this morning suggesting that ‘AV might provide the answer to the otherwise impossible question - if the parties stay together, how can they fight the election apart?’ has caused quite a stir.
The argument is that the Tories would urge their voters to put the Lib Dems as second choice and vice-versa. If this ploy worked — and the Australian evidence Danny cites suggests it would — then AV would hurt Labour not the Tories.
Finkelstein is, of course, a columnist not a politician. But he used to work for the Tory party and with George Osborne; few commentators can claim to understand the strategic thinking of the current Tory high command as well as Finkelstein does. So the question is: are they thinking, what he’s thinking?
