The @nytimes.com , @washingtonpost.com & the rest treat #RussellVought like he's a run-of-the-mill small government conservative. The man is a religious zealot that wants to bring down the state & replace it with an American theocracy out of Margaret Atwood. It's the biggest story no one is telling.
Sunday reading:
I wrote about the aggrieved extremist who is currently firing thousands of federal workers and ravaging state capacity based on conspiratorial nonsense - and about mainstream media’s infuriating tendency to sanitize Russell Vought and the regime he serves.

RFK Jr: We had lots of guns when we were kids. Kids brought guns to school and were encouraged to do so. And nobody was walking into schools and shooting people. There are many things that could explain this. One is the dependence on psychiatric drugs.
