The biggest difference between Pete and Hunter is that Hunter is working a program aimed at helping him live "one Day at a Time," as a clean and sober person, Pete appears to still deny his underlying problem. Someone, close to Pete, should invite him to a meeting. He will not be able to find true happiness, no matter how many Generals he fires, as long as he remains in denial. Stop enabling him. There are many Trump allies who could replace him as the nominee.
