If you repeat it often enough it does not make it true.

AV is supported by the Lib Dems, UKIP, Greens, Plaid, SNP and support for this system as a fairer alternative was in the Labour Party manifesto in 2010. So if one of the campaigns is partisan it is the one that is only supported by one major political party (No 2 AV with the support of the Conservative Party). If is were such a partisan fraud then why is it supported by the leader of your party and your local MP? Have Ed Miliband and Jim Dowd been taken in by a partisan fraud or do they actually care about a fair voting system for the British Parliament?
