Why did Kennedy win and later became President?

John Kennedy's selection of Lyndon Johnson as Vice President, his convincing rebuttals to attacks on his religion, inexperience and health, and Republican errors all had a substantial bearing on the outcome. However, Kennedy won above all because he was Nixon's equal in substance and superior in style. As the first absolutely media-conscious and heavily-marketed presidential candidate, Kennedy was able to impress upon the nation the idea that it had entered a new epoch and that he was its ideal leader.
