Yes, this again. Thatcher was very right wing.........the only Tory right winger to have won an election since the war. (Remember, I conceded this last time we discussed this, only a day or two ago). All the other conservative election winners were "one nation" Tories (whether they said so or not), towards the left of their party, and thus towards the centre ground of the electorate. Blair, the only Labour leader ever to have been re-elected I believe, was to the right of his party, and thus towards the middle ground of the electorate. We could have a discussion about Wilson, but him aside, I can't think of a Labour leader from the left of their party who has won an election since the 50's, and certainly none has ever won re-election.
I don't know why this discussion pains you so much.
