Sorry mate not a lefty
Left has been dead 30 years, so your point is?
John Major's vote went up in 1992, but why were they voting Major and nor Maggie? Where had Maggie gone and why?
If a week is a long time in politics then how much can change in 2 years? I have never claimed that the political reality of the Poll Tax lasted but what political reality ever lasts? People have a very short attention span and a short memory.
Immediately after the Poll Tax the dance music scene suddenly took off and vast amounts of new drugs, supplied by organised crime the favoured and deniable conduit of the intelligence services, became suddenly and inexplicably available to every one. Many people at the time and subsequently did not think this was accidental. The state prefers people bombed out of their minds if the alternative is rioting, and you do not riot on e! Ok I admit I also think Techno is shit so I am a bit bias about this.
In 1992 the Poll Tax had ceased to exist and the Council Tax was on its way in. The media had run the famous grass up a poll-tax rioter campaign and as I said earlier everyone was freaked-out. The "nice" Mr Major replaced the "nasty" Maggie, so middle-England could vote for a someone.....remember the alternative was Kinnock (the biggest lefty looser I can think of!) so the result was a walk over. After all what possible alternative was there to vote for or campaign around?
Kinnock had done nothing about the Poll Tax or the Miners or the Printworkers but had been running witch hunts of Militant. Not a bad thing in itself, a senior member of Militant told me in 1989 that they would achieve a revolution within 5 years and I would be the first to be shot.
However, I cannot understand your arguement:-
An unjust tax is defeated, by accident rather than the left, and replaced by a mildly less offensive local tax
Maggie is booted out of office by her own party
Kinnock did not win the 1992 election
This was a win, win, win situation as far as I can see!
