What? I have no idea at all what you could be referring to.
John Kennedy? All JFK could do to Nixon was using the Democrat election rigging machine - which he did.
Robert Kennedy tried running against Nixon on the "I support the Viet Cong" platform until he was murdered. Ted Kennedy maybe?
What are you talking about?
Jack Kennedy won against Nixon, so using the BDemoTards “new” logic, JFK *must* have “swiftboated” him... ;o^)
