Yeah, from what I understand I living Joe Jr. whether he starts off in the Senate or the Governor's house would be much more of a risk taker than Jack was. I am not sure about wether he was known to be as much of a womanizer as his younger brothers so Id think he'd make a fairly strong President.
At the time of his death he was seeing a married woman. The Kennedy boys had high libidos . . . got it from old Joe.
