A person should be punished for those crimes, if found guilty, irrespective of the motives behind the crimes. If William Clinton had had a sexual affair, but didn't commit any crimes, I would have no problem with him remaining in office. I wouldn't even support censure in this case. This isn't about sex, this is about whether the rule of law applies to everyone, or whether we apply special exemptions for popular political leaders. William Clinton will have and should have an opportunity to defend himself in the Senate impeachment hearing, but if it is found beyond a reasonable doubt that Clinton committed perjury or another serious crime he must be removed from office or the rule of law is a charade.
Censure is a fig leaf, a meaningless slap on the wrist.
If our president is a criminal, he needs to be removed from office or our Constitution isn't worth the paper it's written on.
