The Liz Truss saga is a strange one. Has she genuinely moved to the far right? Is she trying, cynically or cleverly or both, repositioning herself there for a political comeback? Or is there something else going on?
Cognitive dissonance is a powerful force. When we have two beliefs that we are aware strongly conflict we have to resolve it. You can do that rationally, but there are strong mechanisms to do it in other ways.
Liz Truss believes, as most of us do about ourselves, that she is a decent, competent, smart, sensible person with good ideas. 1½ years ago she was humiliated to be told that she was a foolish, incompetent, naive person with bad ideas. This is a strong conflict.
So I think it's possible that she has grasped the populist idea that she was brought down by 'the blob' our 'the deep state' as a way of resolving this dissonance. For clarity, this means not that she's decided to adopt that idea to save face: she genuinely believes it.
