Re 23:
Yes, Barr is wrong 100%, and Powell is wrong 100%, regarding the LEGAL argument.
Barr spared Powell total humiliation and loss of her license. Now Trump must do so.
What people are getting wrong is that political arguments are NOT legal arguments. Powell has bamboozled people by making political arguments. Whether she is just grossly incompetent (probably) or a grifter (possibly) will be for another tribunal to decide.
So you are really saying that you have a better legal argument than the Solicitor General did in his brief. And the members of the appeals panel who issued the initial Mandamus order were wrong too. OK...
