Yes. In theory, that seems to be true. Although, there is a lot of diversity of opinion of opinion within Scotland that rarely ever comes through in Westminster elections.
Devolution should even that out in many ways - giving Scots more direct control
over several key areas of life and enabling the diversity within Scotland to be better represented in doing so.
But the spectre of independence distorts everything in unfortunate ways. And a whole range of changes in the world make
it pretty daft to imagine that Scotland actually can achieve independence without screwing everyone over. Brexit has made many things clear.
That’s without thinking about how internally stagnated and distorted Scottish politics have been by the indie debate. It turns out that devolution has been terrible for those parties that are aligned with UK parties in various ways.
Of course, one of the big problems with how devolution was introduced is that there is no English parliament (or even a set of administrations that break up England). So Westminster is a big of a ridiculous fudge in several ways (and you get oddities like there being ‘UK’ ministerial departments that only have a remit over England). This creates all sorts of problems in relation to how westminster elections are framed.
Labour did make a big of an arse of constitutional reform back at the turn of the century in ways that become ever more obvious as time goes on.
Personally, I think it might have been better for Scottish politics if the pro-indie groups had been able to secure a yes vote in the last referendum. Circumstances would have necessitated better politicians and the break from the UK would have enabled a range of parties to be more effective.
But… just as the indie-lot have refused to let the matter lie post-referendum, I suspect that a yes vote (unless it had been an overwhelming landslide - which it would never be because Scots are more risk averse than we like to imagine ourselves) would just have resulted in ongoing unionist ‘rejoin the UK’ nonsense. And
it wouldn’t be better.
That’s totally ignoring that Scotland would almost certainly have not done amazingly at negotiating scexit and setting up the flourishing small utopia the pro-indie campaigns promised.
Which is to say, I have no idea what the answer is there. And none of it changes the fact that the SNP are a shower of shite.
