Gore didn't finish divinity school because he decided he didn't want to be a theologian. It is not uncommon for one to be in school learning a particular field and then decide that field is not for you. Similarly, he did not finish law school he decided he had no desire to be a lawyer. It was not what he was passionate about. I think it speaks more to his strengths that Gore was able to think independently and make his own decisions about his life, and not be forced down particular trails by societal explanations. Also since you were not in school with him, you have no way of knowing whether he was drinking excessively. Its a moot point anyway, because many of our greatest presidents were heavy drinkers. Read Doris Kearns Goodwin's book on Franklin Roosevelt, FDR drank heavily throughout his presidency and also kept a mistress. This did not make him a bad president. More presidents in U.S. history have probably been drinkers than teetotalers. So your thesis is without merit.
