Would Bobby Kennedy have become President if he wasn't assassinated? Would he have beat McCarthy and Humphrey in the Democratic primaries? Would he have beat Nixon for all the marbles? I think if it wasn't for his assassination, Bobby Kennedy would have absolutely been our nation's President. He was leading in the Democratic primaries when he was mortally shot. He probably would have went on to beat McCarthy and Humphrey to win the Dem ticket. That would have set up the Kennedy vs Nixon matchup. I think that would have been a great election and fairly close. But in the end I feel Kennedy would have defeated Nixon. Maybe not by a lot but he certainly would have won.
