Rapaire, while your list is quite accurate, it is a bit dated. Those caught out in the glare of the headlights/spotlights--or even the light of day--right now are tilting very much to the right.

They have also had careers (recently, at least) that touts the virtues of being highly moralistic.

Hence the hypocrisy.

Lots of folks on your list were just plain, ole drunks. These scandals are about using the drink as an excuse for hypocrisy and double standards. As in one for me, another for everyone else.
