First of all, don’t underestimate the political effectiveness of lies, propaganda and easy solutions to complex problems, right wingers have been using that same technique across the world for a very long time and it does sadly work sometimes.
If the election is the disaster for the Tories that we hope it is it’s also a question of whose left in the party, a lot of the moderates have already left or have said they are not standing at the next election so it there might not be many sensible Tories left to pick a sensible leader, it could well be headbangers voting for headbangers, especially when you have a dwindling, old and out of touch membership who very much buys lies, propaganda and easy solutions approach (see the Truss leadership campaign). So I am sticking to my long standing prediction, they will get hammered at the next election, blame it on Sunak who many Tories see as a centrist (which he probably is in the current Tory Party) move further to the right because they will read the hammering as them not being right wing enough, then come 2029 they will get beaten convincingly again and then move to the actual centre as most people see it.
