The US District Court for Washington DC currently has 11 judges appointed by Carter or Clinton and 5 judges appointed by Reagan or Bush.
Good luck getting quo warranto out of one of the most liberal courts in the nation.
Not only that - the liberal judges in the District court - but Leo is not going to find a prosecutor to take the case before the liberal judge.
I don’t know how serious Leo is in all this. I know he has demonstrated a serious intention to shoot down all the other cases while he has done nothing with a plan that will go no where if he should ever act upon it - which I doubt he will. For me, at this point, seeing is believing with Leo and otherwise it is all a bunch of circular mental masturbation.
