//I expect your vote in 2992 put John Major into No.10, just in time for him sign us up to the EU (without any referendum or consultation with the public).//
Just on a point of pedantry, the Maastricht Treaty was signed on behalf of the UK by Douglas Hurd and Francis Maude (though obviously with the agreement of that Nice Mr Major, who was already in No 10, having become PM on the resignation of Mrs Thatcher in 1990). It was signed on 7th February that year whereas the General Election was not until 9th April.
I did vote Conservative in that election (as I have done in every GE I have voted in). The Tory manifesto of that year promised great things of our membership of the EU - none of which I believed and little, if any, of which eventually materialised. However, the alternative, which would have seen Neil Kinnock in No 10, would have made little difference to any of that. However, as much as any Labour supporter could not vote for the Conservatives, I cannot vote Labour under any circumstances. The only difference is I don't insult Labour supporters by referring to them as "Labour Scum" (or similar).
