John Adams, John Quincy Adams.
William Henry Harrison (Tippecanoe) and Benjamin Harrison.
Teddy Roosevelt, Franklin Roosevelt.

America has always had dynasties since the earliest days of the Republic.
That is my thought, too. We already know them and that both reduces uncertainty about them and lets us believe we can hold them accountable through their better known familial elder.

I tend to agree with you. It also has to do with looks. Kennedy was good looking and Nixon was not particularly and he was old. Clinton was good looking and kinda funny and Bush I was OLD and boring. Bush II was good looking and Gore nor Kerry are not and they are boring. I think it had a lot more to do with the person running against these Dynasties then the actual families actually becoming dynasties.
