I wrote some of the Tories, quite a few of whom had roots in UKIP or ties with it before it became Reform UK.
Farage is hugely responsible for the mess, so I would expect nothing more than for him to try and disassociate himself from it. You’re right, he‘ll muster his charges again and they’ll run in seats at the General Election, but I’m not sure that people will have the stomach to listen to more of him and more of his lies. They might make enough headway to take votes from the Conservatives in certain places, but they’re not going to take seats, and the Tories will be haemorrhaging votes to everyone anyway, so their impact might be much less and certainly not worth the airtime of old.
