I have a right to think that when it is his word against her word and her word and her word AND her word that there is almost certainly something of truth in the accusations. But I would not vote for him anyway, because he is a crackpot and a blowhard. He reminds me of one of the less acceptable presidents of my college. All blather and ego, done in a preacherly style. The president in question was thrown out for incompetence and misuse of funds, but they gave him a nice parachute and allowed him to leave in a dignified manner, which he did not do to some of my colleagues who opposed him. So it is rather satisfying to see this pompous ass get punctured and slowly deflate in public.
If he did not want to be pilloried in public, remember that no one forced him to run for president.
