Yeah it's turning into what I thought it might. He's a drinker who likes to throw a little something extra in when he's partying. If the media would leave it alone it'd likely be a moot point as he seems to do just fine normally. He doesn't handle accusations well though, which is typical alcoholic "I don't have a problem, stop telling my I do" behavior and the media frenzy has all but destroyed his ability to do his job. He's also reportedly brought his partying into the workplace which is unacceptable.
Time to go.
He won't though, he'll stick it out until the end, I don't think he has anything else to do and since stepping down is political suicide he may as well take his chances pushing through and hoping people move on.
