Rapaire..if indeed Clinton's marriage vows did say that, it was likely his wife that he was promising, and thus his wife that he is answerable to...and I gather that she made her opinion clear about the matter.
I don't assume that hoping to slide by a stupid mistake by 'bending the truth' "I did not have **sexual relations** with that woman..." is a sure sign of bad character. It 'may' be, but I'll weigh it in context.

I know that several presidents had various affairs and had likely made similar 'vows'....I just think that the details of the incidents are important when considering how we judge to whole man, and in what context...

(silly example to make a point: If Clinton had been accused picking his nose and wiping it on the desk in his office..'defacing government property', and had 'denied' it, he could have accused of perjury under certain conditions with DNA tests and witnesses....but....) (I said it was a silly example)
