Lyndon Johnson, a Texan who was majority leader in the Senate before becoming Kennedy's vice president, was a masterful politician. He had been schooled in Congress, where he developed an extraordinary ability to get things done. He could plead, cajole or threaten as necessary to achieve his ends. As president, he wanted to use his power aggressively to eliminate poverty and spread the benefits of prosperity to all.  

Johnson took office determined to secure the measures that Kennedy had sought. Immediate priorities were bills to reduce taxes and guarantee civil rights. Using his skills of persuasion and calling on the legislators' respect for the slain president, in 1964 Johnson succeeded in gaining passage of the Civil Rights Bill. Introduced by Kennedy, it was the most far-reaching piece of civil rights legislation enacted since Reconstruction. Soon Johnson addressed other issues as well. By the spring of 1964, he had begun to use the name "Great Society" to describe his reform program, and that term received even more play after his landslide victory over conservative Republican Barry Goldwater in the presidential election of that year. On the economic front, Johnson pushed successfully for a tax cut, then pressed for a poverty program Kennedy had initiated. "This administration today, here and now, declares unconditional war on poverty in America," he announced. The Office of Economic Opportunity provided training for the poor and established various community-action programs to give the poor themselves a voice in housing, health and education programs.  

Medical care came next. Truman had proposed a centralized scheme more than 20 years earlier, but had failed to gain congressional passage. Under Johnson's leadership, Congress enacted Medicare, a health insurance program for the elderly, and Medicaid, a program providing health-care assistance for the poor.  

Similarly, Johnson succeeded in the effort to provide aid for elementary and secondary schooling where Kennedy had failed. The measure that was enacted gave money to the states based on the number of their children from low-income families. Funds could be used to assist public- and private-school children alike.  

The Great Society reached even further. A new housing act provided rent supplements for the poor and established a Department of Housing and Urban Development. An immigration measure finally replaced the discriminatory quotas set in 1924. Federal assistance went to artists and scholars to encourage their work.  

The Johnson administration also addressed transportation safety issues, in part because of the efforts of a young lawyer, lobbyist and consultant named Ralph Nader. In his 1965 book, Unsafe at Any Speed: The Designed-In Dangers of the American Automobile, Nader argued that many cars could cause death or damage in even low-speed accidents. Nader said that automobile manufacturers were sacrificing safety features for style, and he named specific models in which faulty engineering contributed to highway fatalities. In September 1966, Johnson signed into law two transportation bills. The first provided funds to state and local governments for developing safety programs, while the other set up federal safety standards for cars and tires. In all, the Great Society was the greatest burst of legislative activity since the New Deal. But support for the Johnson administration policies began to weaken as early as 1966. Some of Johnson's programs did not live up to expectations; many programs went underfunded. Still, the Great Society achieved some reductions in poverty -- between 1965 and 1968, for example, black-family income rose from 54 percent to 60 percent of white-family income.
