I do not consider Trump to be POTUS.

Yes, Donald Trump won the 2024 elections. He was inaugurated. But in his actions since then, he has demonstrated he has no interest in being a president as mandated and restricted by the U.S. Constitution. Railing against rulings against him, he advocates removing or impeaching judges. Ignoring that Congress established certain functions, he is dismantling them and inactivating them without any input from Congress. He is President In Name Only: PINO.

I call him PINO Trusk, as the office now embodies the worse of Donald Trump — the lying, cheating, lawlessness many of us expected from this shallow, unprincipled narcissist — and the lawless, reckless, ignorant avarice of Elon Reeve Musk. Between the two, the ideals of our nation are being undermined; our history is being subverted; our lives are being destroyed.

Jamelle Bouie expresses it well.

Trump Has Gone From Unconstitutional to Anti-Constitutional
