David Cameron is the best thing to happen to the Tories since the Winter of Discontent
I would actually say that the Labour Party conference of 1980 was a much better thing for the Tories than a wave of public sector strikes.
True, but without those strikes, Thatcher might not have been elected in the first place
Someone on the forum (maybe you?) once said that if Callaghan had held the election earlier (in late '78) he probably would have been re-elected. The strikes were what turned the tide.
Of course Mr Callaghan had higher personal approval ratings than Mrs Thatcher going into an election IIRC. There was a desire for stability that Heath, Wilson and Callaghan failed to provide.
