I'm not sure I'd want to work at a company that has stricter rules against what I do in my own time than the leader of the free world. Anyone with a family to support is likely to conclude that such "high" ideals (pun intended) are a load of B.S.
I don't agree with the actions of Bush or Obama when they were much younger, but there's a difference between some dumbass behavior 20-30 years prior, and someone who fails a drug test for job because he/she was smoking weed 3-4 days prior.
Well, I guess it boils down to this - to each his own hierarchy of important values....
