Dodd was elected as a
Democrat to the House of Representatives in 1952 and served two terms. He lost a Senate election in
1956 to
Prescott S. Bush but was elected in
1958 to Connecticut's other Senate seat and then re-elected in
1964. Before becoming a U.S. senator, Dodd was hired to lobby for
Guatemala in the United States for $50,000 a year by the dictator
Carlos Castillo Armas. According to the North American Congress on Latin America, Dodd "had perhaps the coziest relationship with the Castillo Armas government." After a short trip to Guatemala in 1955, Dodd urged the House of Representatives to increase aid to the country in
Central America. Dodd's amendment passed and Guatemala received $15 million of U.S. aid in 1956. In 1961, Dodd visited the
Congo to investigate the civil war caused by the secession of the
Province of Katanga. In addition to his work in the Congo, Dodd opened what became nearly three years of intermittent hearings. The results of the three committee staff monitoring reports of television content in 1954, 1961, and 1964 showed incidents of violence. Senator Dodd and
Estes Kefauver were the two men responsible for informing the public of the effects of violence on juveniles. In 1964, Dodd was locked in a somewhat bitter and tough re-election bid against popular former Governor
John Davis Lodge, the younger brother of the Ambassador to
South Vietnam and former U.S. Senator
Henry Cabot Lodge Jr., who had just won a series of Republican presidential primaries, starting with New Hampshire earlier that year without campaigning but on the strength of the Lodge family name alone. Worried that this respectful allure might empower John Lodge, Dodd reached out to President
Lyndon B. Johnson for assistance. Johnson had been keeping his choice of
running mate secret and so on the Wednesday of the
Democratic National Convention, before the evening on which the running mate would be announced, Johnson summoned both Dodd and his colleague, whom Johnson had chosen to be his running mate, Senator
Hubert H. Humphrey of Minnesota, to the White House. While Dodd was never seriously considered as a running mate, the ensuing summons by the President added a lot of suspense and free press to Dodd, who successfully used it to raise his name and record before the voters. It also allowed Johnson that much more excitement in naming a running mate, a choice that had come down in the press and public opinion between Humphrey and Minnesota's other senator, the urbane
Eugene McCarthy. Aided in part by Johnson, who enthusiastically endorsed Dodd on a campaign swing through Connecticut later and then Johnson's subsequent landslide over Arizona Senator
Barry Goldwater, who seized the
Republican presidential nomination from Lodge's brother and a number of other establishment Republicans, Dodd won his own landslide over the younger Lodge by 30%, thereby shuttering the younger Lodge's nascent political career. In the fall of 1965, Dodd tried to get
Martin Luther King Jr. arrested for violating the never-successfully used
Logan Act of 1799, claiming that King's public stance against the
Vietnam War was a
felony per the Logan Act's intent of preventing unauthorized negotiations from undermining the government's position. Dodd also sponsored the Drug Abuse Control Amendments and was involved in problems relating to non-narcotic stimulants, depressants, and other psychotoxic drugs like hallucinogens and psychedelics. Then, in the spring of 1966, the Senate Subcommittee on Juvenile Delinquency met to discuss the "LSD Problem" that has been becoming more prominent. Dodd spoke out against the use of psychedelic drugs because he rejected the idea that expanding consciousness was a worthwhile goal. He went on to say that it was all just an excuse to have fun with no serious benefits. Dodd proposed new strict laws to try to keep LSD away from the youth of America. As chairman of the
Senate Subcommittee on Juvenile Delinquency, Dodd worked to restrict the purchase of
mail order handguns and later shotguns and rifles. Those efforts culminated in the
Gun Control Act of 1968, which Dodd introduced, including certain registration requirements. Dodd played an instrumental role in the prohibition of
LSD in the United States by presiding over subcommittee hearings purportedly investigating the drug's effects on youth. Notably, the Harvard psychologist and LSD proponent
Timothy Leary was called to testify. Although Leary urged lawmakers to enact a strictly regulated framework in which LSD would remain legal, Dodd and his colleagues drafted a ban which was later adopted. That event was one episode in the prelude towards an all-out "
war on drugs" in the 1970s. ==Senate censure and loss of office==
