He divorced in 1985, readily available sources don't tell me why, but we'd want to know. He remarried in 2002, so while she's much younger than he is, she wasn't "young" when he married her, so that shouldn't be a problem for too many people.
There are rumors he enjoyed the company of women during his years, but I haven't seen anything in published sources about it. I suppose that could be a problem as well, although my opinion is there probably isn't any recent cheating since he wasn't married from 1985-2002, and I doubt he's been cheating in his last 4 years. He has a child by his latest marriage.
You know what, I COULDN'T CARE LESS. Really. I want a President who will kick some Muslim ass. I was being sarcastic. And by the way, compared to him, she was young shen they married. Still 24 years younger than he is. Always will be!
