I think we may have already seen peak SNP who gained from the anti-labour lurch.
I think many Scots would quite like it, but they look at the level of support that being part of the UK brings and would be reluctant to go it alone.
A lot of SNP voters are Brexiteers and a lot are not actually pro Independence. They certainly aren't pro independence and then join the EUers.
See if the various factions can come together. I sense not, but it's all guesswork for now.
