Oh yeah, they're going to side with him. "Only the President would know when an emergency happens." Not the more obvious, "Congress cannot make a law that hands off Article I powers at the President's whim."
There's literally zero spine left in the Supreme Court. Easy W for Trump here since the Supreme Court cares more about RVs than actually upholding the Constitution.
Oh absolutely, it's going to be a slam dunk W for Trump because the Supreme Court is just going to ignore everything Article I of the Constitution says.
