Currently, two brother are going up against each other for the leadership of the Labour Party in Great Britain. That got me wondering if it would be possible of something like the to happen in America with their most famous political family...
Your challenege, should you chose to accept it, is to have any two members of the Kennedy family go up against each other for the Demoratic Nomination for President. .You can chose the POD, but it must be no earlier than 1959. Bonus points if you can have it cross generational fight between father and son, or uncle and nephew.
