AV or not to AV - that is the question

I always know when a campaign is fishy when I get unsolicited mail from actors or TV 'personalities' telling me what I ought to do. Just recently I received some junk mail (in the truest sense of the word) telling me to vote 'yes' in the AV referendum. The arguments advanced were simplistic and threadbare, not because they necessarily are so but because almost all the space on the leaflet was given to photos of  'celebrities' endorsing the campaign: Steven Fry, Colin Firth, Helen Mirren and Benjamin Zephaniah amongst them. A ship of fools if ever there was one.
