It is the regional variation that I find interesting. Scotland has the SNP. Northern England and Wales are Reform. The eastern half of London is Green. Rest of England is Conservative.
Andy Davies@slowe Would be interesting to match it up with economic depravation
That's where Reform seems to do well and matches my knowledge of the South Wales Valleys for example
Seems to be a reaction against the status quo as I can't really believe the working class of the valleys think rich, privately educated white men are going to their standard of living
@andydavies Yes, I think there will be correlation with people thinking they are reacting against the status quo by supporting rich, influential men.
It can't only be deprivation given that the deprived parts of London behave differently.
Perceived distance to power (and from Government power/spending) will be part of it.
But it is unavoidable that racism/bigotry is also a factor. Most of our politics is happy to stoke bigotry as a way to misdirect blame from the powerful.
@andydavies In the decades leading up to 2016 I watched how our Establishment blamed the EU for things; often things our Government had pushed through in the EU so they could blame "Them" for the result. I watched them also blame "immigrants" for things. So much blame deflection. In the first half of 2016 I pointed out (to many people supporting Brexit) that once Brexit happened it'd be harder to blame the EU so the Establishment would become even more extreme at blaming marginalised folks.
