Personally I disagree that these tax cuts will bring the growth they desire, but there is no point going into it, because I will be misrepresented and patronised to death.
Polls can change, but only if the Tories can regain trust, which is hard to do. Sticking fingers in the ears and hoping in vain is unlikely to do it. Labour won’t be complacent, but they’re not going to go into despair because of hypothetical turn arounds based on nothing. I am sceptical Truss is good enough to turn it around. She’s weak on presenting herself as a strong leader, for one, and I don’t know how she reverses that perception.
