The invert Peter Mandelson is set to replace cross-dresser Edward Izzard in fronting the 'Yes' campaign. Labour's stance on AV to date has been as much a triumph of equivocation as the sexuality of its frontsmen; only hard-line political dags and groupies can tell you whether 'Red Ed' is actually for or against, whilst in the public mind other senior Labour figures are evenly divided between the two camps. In contrast, few could easily identify any Tory figures in favour of AV but there is a high level of recognition that Cameron is against it. Mandelson's strategy for the following week will be simple - to identify Labour wholly with the 'Yes' group in an attempt to turn the Referendum into a straight Labour-Tory vote; if he succeeds, the 'No' camp's solid lead will wither over the next week as an appeal to tribal loyalty overcomes a cross-party neutrality.
The tactic is pure, classic, poison Mandelson and indicates the desperation of the 'Yes' group. He's prepared to sacrifice the cred of any Labour figures on the 'Yes' side (and no doubt will rejoice at any political harm he can do to John Reid) and accustom disenchanted LibDems to voting in the Labour lobby. Loathe him or loathe him, there's no denying that Mandelson's still one of the sharpest political manipulators around.
