I think their origial plan was to try and ensure that Daniel Korski, the CCHQ preferred candidate, would get selected by putting him up against insane choices like Susan Hall. Unfortunately Korski had to exit because of sexual assault allegations (name a more iconic duo than Tory politicians and criminal sleaze) leaving only the insane candidates.
This sort of situation has become a bit of a classic Tory tale with the amount of times similar things have happened since 2019.
