Harriet, please shut the fuck up. The Labour party has enjoyed an electoral bias for fucking years. It's so well known that in opposition the Tories need a swing of ≈5% just to draw level with labour that even your unofficial mouthpieces at the BBC don't try to hide it, and indeed have discussed it openly while covering every general election I've watched. Oh, I don't doubt that the Tories will benefit from any change and would love to gain a measurable advantage over you, just as your shower of hypocritical cunts have enjoyed such an advantage over them for years, but to gain any real advantage would require changes that politically they probably don't think they can get away with. Redressing the balance and getting something that's more or less parity is about as much as they'll get away with this time.
So I repeat, Harriet: please shut the fuck up. Because this is the second time this week I've felt the need to defend the Tories against pot and kettle bullshit from Labour and it makes me feel like I need a wash. If you felt so strongly about this, if you had this wonderful love for democracy, why didn't you attempt to fix it while your teams were in orifice? Why didn't you even speak out about it?
Sauce for the goose, Harriet. By all means come back and whine about it when Labour's been hamstrung by 5 or 6 points for a decade or so, but until then, fuck off.
P.S. - I should add that this idea about not having to be on the electoral roll is just formalising things for all those millions who don't vote at all, and judging by a look I once had at MPs who were elected on less than a 50% turnout in their constituencies these dedicated non-voters live mainly in seats which are fairly safe for Labour. Doesn't seem likely to hurt Labour very much and from the point of view of the individual voter the effect on democracy is about zero. After all, what's the difference between them being registered and not voting for anyone and being not registered to vote at all?
P.P.S. - Guido points out that Harperson is basically suggesting that Labour voters are too thick to fill out a form all on their own and need the brightest person in the household to do it for everyone. Not sure she's looked at it quite that way.
