Jack Kennedy, was sort of an absentee Representative in the House. Somewhat bored and loved being a bachelor and enjoying the Washington nightlife when Congress was in session. It wasn't until JFK decided to run for the Senate in 1952 that he started taking his job more serious and making his positions known in Congress. There are a lot of things to love about Jack Kennedy and he is my political hero, but he's definitely someone who grew in office. Wasn't a great Representative, but a good Senator at least in the sense that he started taking issues seriously and studying them and not just going to his committee hearings, but knowing the right questions to ask. I don't believe JFK becomes President of the United States on his personal appeal and family name alone in 1960, had he not become a serious Senator and taken his job in Congress seriously and getting on the road and getting his political platform out there.
I'm not sure JFK gets into his politics without his father Joe pushing him. But it's clear that once JFK got into politics and ran for the House in 1946 and was elected he loved it and became a natural campaigner and politician. He gave a great speech, great interviews, knew how to excite and inspirer people. He wasn't a natural public servant and someone who actually loved doing the job that he was elected to do. He tenure in the House is a pretty good example of that. I believe he sort of grew in public service once he was elected to the Senate, especially his second term when he started considered running for president in 1957 or so. But was someone even though had a fairly thin resume outside of Congress and somewhat of a thin voting record and list of accomplishments in Congress, was someone who was great at expiring people and laying out a vision for how America could be even greater and how all Americans could succeed in America.
