The US had DONALD FUCKING TRUMP as president and yet the UK is falling apart and the US isn't.
The Tories have been in charge for 20 years, most of which with a huge majority. They have passed every law and every idea that they wanted and as a result they lost their credit rating, (not hyperbole), Brexit happened (economically worse than policy the US has done since the 19th century), the countries infastructure is fucked, healthcare (Hospitals, nurses, doctors), schools, roads, post, army are all at the brink of total collaspe at the same time
Utterly botched covid response. Inflation out of control, the value of the Pound in freefall, Gig economy destroyed, standards of living in the biggest decline since WW2
And the government's literal response is "It's not our fault, damn immigrants and transgenders." They have no plan, no real policy. Just bigotry
How can you claim the Republicans are less deluded?
This isn't even coming to bat for Republicans. It's just the Tories for the past 20 years have been the most incompetent political party of any 1st world nation since the 1950s.
That is not hyperbole. They are legitimately that bad on every level.
How much autonomy do individual parts of the UK have to be run by other parties (serious question, I don't know)? There is a gigantic gap between red and blue states in the US, deep blue states were able to shield themselves from a lot of what Trump did or tried to do because Democrats were in control of them. If Republicans had more direct control things would have gotten a lot worse.
