Hard to separate private life stuff from public life stuff. We have no idea what may happen tomorrow but it is reasonable to make assumptions on how a politician will handle the situation by looking at how he handled issues in the past.
Your comments on Bill Clinton are somewhat offensive. I personally don't care what he does in his private life but when someone shows a proclivity for going after women who works for him then it indicates a tendency to use the office for personal gain. The French have the right idea, surprisingly, and consider adult consensual relations between an employer and employee as felony rape. The is a obvious power difference and the subordinate either complies in fear of repercussions (unstated or not) or hopes of some favorable employment benefit. And co-workers are impacted. Clearly not a private personal matter that only concerns a spouse.
