About sums it up.
I'm sort of of the opinion that I don't really know if it's worth it, plus I'm scared that it will make Parliament more likely to lead to more coalition governments which scares me slightly as in countries where that happens voter satisfaction and the feeling of democracy is taken away from the electorate and put into the hands of men in suits in parliamentary back rooms.
At the same time I like, in theory at least, the idea of the parliament being more proportional and the idea of taking away the need for tactical voting.
IE in my home town it was Staunchly Lib Dem with the Tories a wee bit behind and then Labour where so far behind they weren't anywhere near being in contention. Meant that if I were voting there last year I would have had the choice of either voting Labour (who I support) and the vote being wasted or voting Lib Dems just to keep the Tories out (And I am very aware of the subsequent Irony!), under AV I would be able to still vote Labour but manage to vote Lib Dem as my second choice so at least my vote would count.
They've used various proportional systems for the Scottish parliament and it works but is far more proportional than simple AV would have.
All in all I haven't yet decided which way I'm going to vote. Bit annoying that the vote here is on the same day as the Scottish election as it means no-one here is really talking about it, all the Scottish politics programmes and Scots newspapers are talking about Holyrood not about AV.
Did enjoy the debate between Robert Winston and Eddie Izzard on the Andrew Marr show yesterday morning though.
