It'll be interesting to see the extent to which it comes down to the SNP leadership candidates' strategy for trying to get independence. Humza is on the fence re the election being taken as a de facto referendum, Forbes is the opposite and Ash Regan is clear that she would continue the de facto referendum policy.
Sturgeon is marmite. She has many devoted followers but is seen by others as overly controlling, cunning and aggressive. And of course, caputured by the trans allies.
The contrast between her covid communications and Doris' helped her, but when the longer and harsher restrictions in Scotland continued without any tangible benefit she must have lost some support.
SNP politics in general seems to be to be seen to be more progressive than whichever government is in Westminster, at any cost.
