Ted Kennedy first faced a Democratic Party primary challenge from Edward J. McCormack, Jr., the state Attorney General. Kennedy's slogan was "He can do more for Massachusetts", the same one John had used in his first campaign for the seat ten years earlier. McCormack had the support of many liberals and intellectuals, who thought Kennedy inexperienced ("I back Jack but Teddy ain't ready") and knew of his suspension from Harvard, a fact which subsequently became public during the race. Kennedy also faced the notion that with one brother President and another U.S. Attorney General, "Don't you think that Teddy is one Kennedy too many?" But Kennedy proved to be an effective street-level campaigner. In a televised debate, McCormack said "The office of United States senator should be merited, and not inherited," and said that if his opponent's name was Edward Moore rather than Edward Moore Kennedy, his candidacy "would be a joke." Voters thought McCormack's performance overbearing; combined with the family political machine's finally getting fully behind him, Kennedy won the September 1962 primary by a two-to-one margin.
