I have never voted for the winning candidate in a general election.
Neither have I! (Well I'm a bit hazy about what I did with my first ever vote in 1974 but I don't think I did.)
For many many years I voted in Motherwell and Wishaw, which was a seat where they simply weighed the Labour vote. I remember in about 1987 having an argument with my mother about the whole "wasted vote" thing. It went like this.
Mum: Are you really coming all this way just to vote SNP? (I was living in Hertfordshire at the time.)
Me: Well I'm certainly not coming all this way to vote for any of the others, I could do that in Hatfield.
Mum: But they say it's a wasted vote.
Me: So? Are you going to vote Labour?
Mum (basic socialist principles but utterly scunnered by the corruption and nepotism of the local Labour party): No!!!
Me: So who are you going to vote for then?
Mum: Well I thought I'd give the LibDems a try.
Me (trying to smother the sarcasm): So you think their candidate is in with a chance?
Mum (realistically): No.
Me: Well in what way is your LibDem vote less of a wasted vote than my SNP one?
Mum: Er, um.
Me: Here's how I see it. We all know who's going to win here. If you think your vote is wasted unless it goes to the winning candidate then you have to vote Labour. Which neither of us is prepared to do. So given that, I'm going to do the only thing I can do with my vote which is give it to the party I support, the party I want to win, so that when they announce all the final tallies of votes at the end of it all, mine is in the tally of the party I support.
Outcome? Mum came to meet me at the station on the Thursday evening wearing a tartan skirt, and she had already persuaded two neighbours to vote SNP with the same argument. And indeed in that election the SNP did go from a poor fourth to second place in the constituency (although still a long way behind Labour). She voted a straight SNP ticket all her life after that, and lived to see the 2011 landslide for Holyrood.
Fast forward to 2006 and I physically moved back to the house my vote had been registered in all these years. But another move was on the cards and just before the 2007 Holyrood election I moved (with mother) to Peeblesshire. The SNP didn't win that constituency seat on that occasion, but it did win it in 2011 (the year of the big landslide).
The 2010 Westminster election was situation normal, except that now I was voting in a safe Conservative seat rather than a safe Labour one. I was at the count in Dumfries getting slightly sozzled when we came fourth. Story of my life.
But then in 2015, big upset. My old constituency turned yellow with a vengeance and went SNP. The SNP MP held the seat in 2017 and is tipped to hold it again next month. Meanwhile I'm still stuck with never having voted for an MP who has won their seat, even though we did get within 800 votes in 2015. I don't suppose 2019 is going to be the year that changes either. Sucks to be me.
