I like the Greens. I'd like to see them have a lot more power in this country.
The snag is, as soon as the Greens look as if they may eventually become very popular, unpleasant things will move out from under their stones, and join up. Blair, for example, was a Tory at Oxford, but somehow sneaked into the Labour party and destroyed it from within. Clegg pretended to be this amazing new kind of politician, but then turned out to be just another Tory. Danny Alexander is a Tory. You are only too familiar with the picture.
Infiltration has a long history in British politics.
So, what should you do if you are a Green? And, by the way, you should be sort of Green-ish, unless you want the big, round thing we stand on to become unable to support life. Simple. The next election will be won by Labour, if we are allowed to have an election at all by the robber barons. And if Labour has the sense to announce a glorious vision of our future, instead of wibbling on and on about slight adjustments it would make to fascist oops, Tory policies.
So, my Green friends, it may be time to join Labour as well, and chuck the earlier infiltrators on the scrap heap. Sorry, compost heap...
