Stephen Miller works for Donald Trump, and supports his program. He is often interviewed and he is smart and incisive in his critique of all matters woke.
On the other hand, he is personally one of the most repellant individuals popping up with frequency on TV, nearly as bad as Maxine Waters. He may be talented and a hard worker and loyal, but in his public appearances he is visually the anti-Trump. I find him unlikable.
By contrast, I don't like anything Zohran Mamdani advocates, his disparagement of police, his support of socialism, his pro-Hamas stance. I think he will be a disaster for NYC.
But he has good social skills and he makes a good appearance on TV. His smile has to be worth many thousands of votes. He is likable.
If I were Trump I would keep Miller in the back office, and let JD Vance and Marco Rubio do the public stuff that Trump doesn't do himself.
Charisma, or "rizz," perhaps shouldn't matter, but it does. In my opinion, Stephen M. doesn't have it.
