I don't agree. A lot of people in the red wall by nature deeply loathe the Tories and "lent" their votes in 2019. The Tories have rewarded them by diverting levelling up funds to rich southern constituencies, fucking up brexit and otherwise fucking them over. I doubt those "lent" voters will ever go back, especially if Reform are providing the more right wing of them an attractive option.
I think a lot of other people feel properly burnt by austerity then Brexit and will struggle to forgive the Tories for that either. I know I'm unlikely to vote for them ever again.
They've bought this on themselves and people would be very foolish to expect any of this damage to be fixed quickly. I think Labour will do 2 terms easily. And given global warming who knows where we will be in 10 years time.
