My point is that unionists felt safe voting SNP in all those elections because they knew an independence referendum was not in their gift. I believe this should be a potential outcome that is known before people cast their ballot.
I can not comprehend how anyone, unionist or otherwisw might not have known, given how clear they have been about it, how clear opposition parties have been with their threats pointing it out constantly, and all the repeat complaints about that being 'the only thing the snp focus on'. There was zero doubt.
Edit. 'Oh sorry Boris, we didn't realize you were going to pursue brexit now you've won a majority, can we wait 5 years till the next general election, then tell us again, and we'll know we are then voting for it'.
yeah, might just work. if VAR oversaw politics!
