Well, triangulation seemed a brilliant wheeze at first, since then Labour could be Tory-lite, appeal to the middle-class, and yet keep the old Labour vote, in the ex-industrial 'heartlands'. However, as NS pointed out, Cameron then triangulated back, and also both the Nu Labour voters and the Old Labour voters began to feel that it was a bit blurry and ignored them. 'Between two stools' is quite apt. Scotland was lost completely, other voters went off to UKIP, and of course, some back to the Tories. Why vote Tory-lite when you can have the unadulterated Blue Essence?
It is interesting to see the reversal now, although who knows where it will all go. Ironically, Corbyn is not hard left at all, but moderate Keynesian, but then Keynes is now considered left-wing, so far has politics moved to the right.
Why have we got a thread on Hitler going on in the middle of this?
