He can ask for her recusal, and file an appeal when she inevitably refuses

Yeah, because when that doesn’t work, and it won’t, there’s no way both she and the violent Trump cult retaliate against him for trying 🙄

He hasn’t even tried that, and at this point, the valid reasons why have all vanished

Yeah, because an already belligerent judge becoming openly hostile helps his case and he isn’t getting enough death threats already 🙄

There’s no chance this case is going to trial before the election

And thus no chance it ever happens unless Trump loses again and the inevitable second coup attempt isn’t successful.

She’s already as hostile as she can be towards the prosecution

Wanna bet? A thousand bucks says she’s still trying (unsuccesfully) to appear impartial and will become much worse in reaction to him stating the obvious facts to the contrary.

And she’s holding hearings regarding having him removed from the case

Does that sound to you like the action of a well-adjusted person who won’t react to valid criticism by abusing the power she has over him and the case?

He literally has nothing to lose

Except for one of the most important and on paper strongest court cases in the history of the country. Just tiny things like that.

What the fuck is he waiting for?

For people more powerful than him to protect the case from the inevitable fallout of an attempt doomed to failure.

Tl;Dr: you’re right about what SHOULD be, but wrong about what IS on all points.
