I don't know how old the rest of you are. I'm 55.
In 1979 I was just too young to vote and watched in horror as Mrs Thatcher took power. Looking back now, it seems less surprising, after the endless industrial unrest of the 70s.
I was young and naive when the 1983 election came around. After the seismic changes the Thatcher government had pushed through, I thought Labour must have an excellent chance of winning. What I hadn't banked on was the power of self-interest (council house sales etc etc), the SDP diluting the Labour vote, the Falklands effect and the utter lack of appeal to the average voter of the far Left policies in the Labour manifesto - described by Gerald Kaufmann as the longest suicide note in history. Militant, a Trotskyite entryist organisation, was massively influential on Labour at this point. Thatcher got re-elected with a much increased majority.
In 1987 Labour was once again trounced, for the same reasons. It began to look as if Labour could never be elected again.
In 1992, having gone through the painful process of expelling Militant, and on a far less Left-wing manifesto, Labour was narrowly beaten but was able to exert a far greater influence on the minority Tory government over the next five years.
In 1997 Blair won a landslide victory. I don't approve of a lot they did, but they had power. They were able to actually implement what was in their manifesto. They won again in 2001 and 2005.
And now here we are again. Tories doing things that ought to make Labour really attractive. Labour utterly failing to capitalise on this golden oppurtunity. Right back to where I came in. Incredibly depressing.
