But, they will say, all of this, good as it is, is outweighed by their concessions to the dark side. The wars, especially the war with Iraq; the complicity in torture; ID cards; more surveillance; utterly beastly treatment of asylum seekers, and most especially of their children; the sucking up to the rich; the casual minor corruption. Some of these may have started as concessions to the Americans, and the Tory Press, but they have stained Labour irrevocably and rendered them unfit to continue in office, or to be supported by other cleaner parties even if doing so brings electoral reform and an end to the sort of parliamentary dictatorship which made this sort of thing possible.
They will say that the Labour leadership - especially Gordon Brown - are criminals and should be in jail, and not in government.
And I listened, and was persuaded of the truth of much of it. And did not vote alongside them in the end because I would rather sup with the devil I know.
I am tempted to say this - if you deal with the Tory party, you are dealing with a government which - with the sole exception of ID cards maybe will do all this and more, and do it enthusiastically rather than in the face of its better angels. If you go into coalition with the Tories, even if you get electoral reform - and my judgement is that they will string you along with promises and never actually deliver - they will have dragged you into the sort of complicity with the appalling that Tony Blair and his clique dragged Labour MPs and ministers into.
Like New Labour, you will gain power and lose your souls. And it may look like the clever thing to do, as well as the right one, but it is neither.
Remember Jeremy Thorpe, who thought he was a very clever man, and ended up being dragged to disgrace by a dead dog.
Whereas, because Labour people are not, unlike the Tory leadership and most Tory MPs, scumbags deep down to the bottom of their souls (except possibly Peter Mandelson), you might make their working their redemption the price of doing a deal and PR only the fringe benefit.
I've read posts that argue that there are areas in which the LibDems and the Tories have policies in common = the pupil premium, for example. Let's take that as an example for a moment - up to yesterday the LibDems were arguing that their version of this policy was wholly different from the Tories', which, it was claimed, would be a disaster. If that was true, it remains true, and is it really going to be possible to negotiate a compromise policy here. Or with Trident, or immigration, or Europe - Labour does bad things because they think they have to to gain office, and maintain it, and because they get impatient with people and want to make them better, dammnit, whereas the Tories do them BECAUSE IT'S WHAT TORIES DO. Along with fox-hunting and breaking glass.
The good thing about the LibDems going into coalition with the Tories, or acting as their silent accomplices, would be simply this. No more virtue - you'd be in the blood and mire with the rest of us.
