Re Judge Cannon throwing out the documents case: dh says that a lot of US commentators are suggesting it might be a good thing 
As a loyal Trumpite, she was doing all she could to delay it
and would've continued to sabotage proceedings. 
Smith will already have his appeal ready. If once it succeeds, they'll get a different judge and will maybe be able to make more progress.
I'm not as confident as dh
. My fear is that Trump will succeed in getting away with it due to the Supreme Court's immunity ruling.
