So it is as you described. Labour, Tory and Lib Dem pretty much irrelevant at present. Nicki will have more problems with her own party than the others. I'm not sure how the Salmon stuff will unravel. Whist he was found not guilty, he is by no means faultless. He is a pretty unlikeable individual and is one of the main reasons the nats get the reputation as being anti english (he certainly was and didn't try that hard to hide it). Imo Nicola is a far more capable politician. She will also come under pressure from the party regarding the timing of indy ref 2 (there is a faction that believes she is not fast enough). Whatever, right now she has pretty high credibility and poll ratings through her handling of COVID, despite the fact that their were similar issues with timing of lockdown, PPE and care homes. Her communication with the Scottish people has been clear, consistent and adult.
So I think if there are Scottish elections next year, SNP will show a very strong performance which shouldn't be seen particularly as a mandate for indy ref 2 (but will be) but that they are the preferred party of government in Scotland despite a pretty shoddy performance in the last parliamentary session (Education in particular).
In terms of independence. Its very much about head and heart. On the heart side, Johnson has ensured that even former tory voting centralists like me would vote for independence just to get away from his dishonest and corrupt government. A great deal of people who voted no last time would be thinking very seriously about it now.
However, and it is huge however, set against that is the fact that many scots will want to see the independence proposals. The practical stuff. Financial, Currency, Central Bank, the overall plan, the relationship with Europe, the relationship with the remainder of the UK. Some extremely meaty stuff in there. I have had a number of sensible discussions about independence on here, so not everyone looks at this in an unintelligent way. Some of those that I have conversed with previously underestimate the damage that this Tory party has inflicted on the Union. Another two years of Johnson and his sycophants may just seal the deal. Many of us would pay through the nose just to be free of his politics.
Stand back and wait for the flame throwers ;-)
