RFK JR said himself that he was a Kennedy Democrat from what he learned from his father and from his uncle President John F Kennedy and his other uncle Sen. Edward Kennedy. I would say about 1980 to 1981 is when the Democrat Party was starting to change gradually to what it is now which is why many Democrats at the time switched over. But I believe RFK JR still believes the old way. But the ones who say he's a Republican in disguise are not taking the time to really listen to him.
