[[Rapaire:
If a man or woman in power is unfaithful to his or her spouse, how can I assume that that person will be faithful to his or her oath of office?]]

Actually, Rapaire, psychologists have done quite a bit of research on honesty, lying, etc., and the usual finding is that people's ethics and honesty (or lack thereof) is not consistent across all situations and issues.   There are, indeed, many people who will lie in and about sexual matters but not in business -- and vice-versa.
