S3, The Kennedys are like the American version of the British royal family. The son of JFK would have been presidential material for the Democrats. Unfortunately, his life was cut short by an airplane tragedy. Nonetheless, the grandson of JFK would most likely have the power and charisma of his grandfather. This is shown in the jyotish chart of JFK himself. I would hope that he has a longer life than his uncle and grandfather.
Also, the political parties over here like to select candidates for presidents with name recognition to get the votes. Specifically, there's a nephew of George W. Bush who has political ambitions. The Republicans would probably like to see him run for president since he most likely would be able to get many of the Hispanic votes.
