He can't stay in office "forever" but he can stay in office until he stops breathing...and it's likely he'll try to pass it on to one of his spawn!!!

If he tries he'll succeed...he has all of his pieces in place...from his unitary executive believing Attorney General, to a boot licking Defense Secretary, and a Joint Chiefs who are too chickenshit to actually do anything to support or defend the US Constitution...his cabinet will back him up, and his Vice President will be having tea with his "Mother" most of the time. And lets not forget the courts, especially the SCOTUS, they'll be ruling in his favor until he chokes on a Big Mac!!!

It's not delusional, it's not far fetched, is very possible that he won't step down and that no one will stop him...
