She's wormed her way to the top of the dung-heap that is New Labour, and is to be the 'face' of the party for the already-started 2010 election campaign.
And with her smug, patronising, well-fed face, she seems ideal for the role.
Doubtless she'll be deploying every weapon in Labour's nasty little armory to smear the opposition, to lie about others' intentions.
One of the weapons already wheeled onto the battlefield has been the clumsy and unsubtle 'class war' approach: you know, the one that says that because some Tory politicians were born to parents wealthy enough to send them to private schools, we should all vote Labour. That one.
In spite of being educated at one of the very finest private schools herself, Hattie has clearly been itching to deploy this desperate piece of spin, and yesterday, when Boris Johnson announced fare increases for public transport in London, she saw her chance.
Ms. Harperson, writing in last night's Evening Standard, claimed - with a straight face - that these increases were:
"..Fare increases for hard-working Londoners, tax cuts for the richest"
Oh really? Fucking really? Notice how the 'hard working' phrase is slipped in there. Presumably the lazy Londoners will be allowed to pay reduced fare, will they Hattie? Or is that just a little dog whistle, a little coded message for us?
And what about the 'tax cuts for the richest', Harriet? Do you mean Johnson's decison not to charge 4x4's extra on the Congestion Charge? Is that your idea of a tax cut for 'the richest' then?
Anyone that drives a 4x4 is among 'the richest', and anyone that rides on a bus is a 'hardworking Londoner', are they?
Oooh, thanks for making the politics of envy so very, very simple Harriet.
Are you a 'hardworking Londoner', Hattie? When did you last ride on a bus? (Although of course, you might have to soon, if you actually get the driving ban you so richly deserve for crashing a car while using illegally a mobile phone, eh?)
And, then of course, Hattie spins further, further, higher, higher and states that:
"What [Johnson] does in squeezing the London farepayer today is what Cameron plans for the country were he to win the general election."
Oh for fuck's sake. Desperate, Hattie? How did you get that idea, sweetheart?
"The reason for the fare increases is Johnson and his disastrous Tory priorities.."
Oh, is it? Is it fucking really, Hattie?
So it's not because the newt-fancying piss-head pinko Ken Livingstone pissed millions up the wall while Blair ignored him, then?
It's not because of the monstrous fuck-ups in the PPP scheme a couple of years ago, then?
As the Standard's own editorial points out:
"..the collapse of the failed Metronet consortium in 2007, part of the PPP scheme, has put huge pressure on Transport for London finances. And the architect of PPP was Gordon Brown, when he was Chancellor"
Oh. Oh dear, Harriet. Did you know that, love? Of course you fucking did.
You just thought the we'd be too stupid to rememember that, and that we'd swallow your little 'Boris is a wicked toff' spin without question.
The Standard editorial concludes with a little reminder for hypocritical Hattie:
"Ms Harman should examine Labour's own record on London's transport system before attacking Boris"
That's quite a polite message to 'Ms Harman' ; CF has an alternative, pithier version:
Shut the fuck up, you silly bitch.
