Oh, then you definitely missed some things man, especially if you're putting alcohol abuse in quotes as if he didn't pass a basic threshold for it - much less the bar (hehe) for someone appointed to make potentially catastrophic life-or-death decisions using the world's most powerful military in history. After reading what I found below, I can see more of why several of his own Republican colleagues even had some reservations about his appointment to SecDef.
Apparently, he was pushed out from both of the veterans advocacy groups he ran. The first, Veterans for Freedom, for
mismanaging funds and losing the trust of donors (apparently while managing less than ten employees), and the other, Concerned Veterans for America, for routinely showing up to official events trashed to the point of passing out,
being literally carried out of venues, and even calling for the deaths of entire religious groups
.
So yes, I think on paper his educational and military pedigrees don't look bad, but I think it's reasonable for anyone to be leery of appointing someone who would've have been disqualified on personal conduct and alcohol abuse alone from accessing or working in a good percentage of the national security activities he'll now be in charge of overseeing and directing.
