You have to remember that Truss herself is not RW and Boris isn't even RW. The problem is the party leaders have been opportunists who don't stand a chance without the fringe support.Good to see that there are decent people in the Commons and there are many more like him who are rightfully angry where the RW elements of their party have took them.
It destroyed Theresa May and now Truss is going the same way. It's her own fault really because she only got through the parliamentary party rounds because she was willing to appease these loonies. Boris successfully contained them but that's because he was a liar who had zero principles except how to work himself into the highest of places.
What has taken hold of the Tory party is a mismatch of bullies and yesmen/women who will seemingly do anything and everything to cling onto their jobs. This results in prats like Jacob Reese-Mogg still wielding power. Centrists like Truss and Hunt would never usually take on these people but they have to and it doesn't work.
If you go back, there's also people like Rory Stewart, Anna Soubry, Ken Clarke.... They were all forced out by this mob as well.
It's time for an election and the best that can happen is the vast majority of these morons get a taste of their own medicine and they lose their seats.
