I think Scaramucci might be alright as he seemed to serve a legitimate purpose by cleaning house.
He was supposed to get dumped. He came in, acted like a wild man, fired a bunch of non-MAGAs, said something outrageous and got canned. He was brought in to clean house without it blowing back on Trump for firing people. Scaramucci fired them, went nuts, media blamed him, Trump fired him, hence the "Scaramucci effect."
