It'd been getting very slowly worse for a long time already, tbh. Slow burn build as her sense of interest in politics grew and her identifying with the left became stronger. That is to say, the trend started long before Bernie did what Bernie does.

She still has some worthwhile takes in there with the rest of the shitposting, but it's getting harder to pretend she isn't falling more into that trope as time goes on.

Honestly, I think it's the anxiety.
