Welcome yourself into the new modern crisis
I don't. It doesn't matter. The vast majority of constituencies have a majority of more than 10%. There are 141 marginals out of 650 seats and only 37 of those were 3 way marginals in 2017. So if you live in any of the 613 seats that were not 3 way marginal you have only 3 choices - vote for candidate a, for candidate b, or chuck your vote away.
It won't work. It never has. The Green party has one safe(ish) seat in Brighton. Current predictions are that there are 3 more seats where they have a chance of winning.
It does matter where I live because the claim was that by not voting Labour I was enabling the Tories. You're the one who brought up 'my area' and the plausibility of Labour winning.
What are your criteria for a marginal / 3 way marginal and why do you seem to assume I don't live in one?
