A load of my friends asked me yesterday why I was voting 'Yes to AV'. They were worried that a YES vote would make it easier for the BNP to get elected. I explained how the BNP was campaigning for a 'NO' vote, that they were more likely to be elected under FPTP. I hope I convinced them. Then I came across this video.
It makes the point simply and clearly. I've just sent it to them. Hope it does the trick.
Mind you, I think they could have chosen a slightly more positive voice over..
