I'm sure some do, and it probably (well obviously) doesn't stop there either i.e. the Idaho senator/bathroom stall incident, the Monika Lewinsky debacle and so forth. Without straying too far from the original question, yes I'm sure they do. And maybe that's not too bad of a thing, in general compared what other type of activities they could be involved in.

I have no problem with them smoking a little weed and getting a piece of ass (call-girls or whatever) from time to time if it helps them keep their head on straight, rather than getting into some crazy weird things. But I would hope they would try to keep themselves to a higher standard.
