Here's the first thing you'll see on No2AV's website today:
I've pointed out three unequivocal lies that they are peddling. I'll go through them:
LIE 1: The Electoral Commission (which runs elections) don't say we'd need buy expensive voting machines - Channel 4 News has looked into this and rated it as 'Fiction'. Even if we did, they wouldn't have to be bought from Electoral Reform Services Ltd (the commercial arm of the Electoral Reform Society, which has been campaigning for change to the voting system since 1884 and is helping to fund the Yes campaign). A quick Google found plenty of other providers.
LIE 2: First, Nick Clegg is not going to be Lib Dem leader forever. Second, the Lib Dem leader only gets to "choose the government" if there's a hung parliament, and as Prof John Curtice has pointed out, "only in 2010 – when first-past-the-post also failed to deliver a majority – would a hung parliament have occurred under AV" since 1983 when pollsters started asked about second preferences. Third, it will be you who decides whether or not there is a hung parliament. Fourth, the Lib Dems are only in a kingmaker position if Labour and the Conservatives refuse to work with each other.
LIE 3: No2AV have made up the figure of £250m. £130m of it is for those fictional voting machines. £90m is the cost of the referendum itself (and that doesn't magically get refunded if you vote No), and the rest is for "voter education", based on the education costs of STV, not the simpler AV.
I also take issue with the suggestion that AV is "unequal" and not "one person one vote". AV elections have multiple rounds until the winner with over 50% of the vote is found. In every round it is one person one vote. I won't call this a lie, as it's more spinning the truth.
No2AV have had all this pointed out them repeatedly. For instance, I left a comment a week ago on their 'blog' piece attacking Nick Clegg. (Why can't they play the man not the ball?) It was instantly "flagged for review" and still hasn't been published. I've contacted them repeatedly on Twitter to ask why not, to no reply.
Despite all this, No2AV say they act "the spirit of open and honest debate". There's little sign of it so far.
