<<Isn't POTUS higher than a judge?>>
Oh my goodness, Utilitas!  I've been giving you too much credit.  I suspect many of us here have.  No: the president is not higher than a judge.
The founders devised and encoded in the Constitution a government with powers divided among three EQUAL branches.  This is basic civics.  You are in over your head here, Utilitas; but at least I understand better now why so much of what you post makes so little sense. When you write about the history and government of the United States, you literally don't know what you're talking about.
Here's a place where you can begin your remedial education in civics:
