Don, my imperfect grasp of mathematics certainly ensured that I would (rightly) never be entrusted with important engineering decisions!
I might have phrased things better by saying that more people wanted a Labour government than a Conservative one. I actually agree that our present electoral system, with its exaggerated majorities, needs changing. There is no way that Thatcher would have got away with her sweeping privatisations had PR been in place. It would place an effective brake on any government's more extreme policies.
On several issues, the Lib Dems had more atractive policies (to me) than Labour. I would certainly have voted for them had I been living in a constituency in which they had a chance of edging out the Tories.
As I am very pro European, the reason you gave for getting the UK into European Union more deeply, was very alluring. It would indeed put put more clear, blue water between the sillier US policies and ours. I detect a note of irony in your post though!
