Jack Kennedy running for president in 1960 because he thought it was the most important job in the world. And that if he was going to be able to do the most for his country, serving in Congress even both in the House and Senate that he did for a total of fourteen-years in Congress was not going to be good enough. That he needed to be President of the United States and that America needed to be an example in the world when it came to freedom and take the lead in showing the dangerous effects of communism.
There are more reasons why Jack Kennedy ran for president in 1960. He thought the country was starting to fall behind Russia in some key areas like with exploring outer space and perhaps in technology and influence in the world. And that the Eisenhower Administration had felt satisfied with how things were going in the country, which is how Senator Kennedy felt. And that America needed to get moving again and he believed he was the person to get America moving again.
