Was Lyndon Johnson more effective in domestic or foreign policy? Why?

Lyndon Johnson's
domestic policy was certainly more effective than his foreign policy. President from 1963 to
1969, he replaced John F. Kennedy after the latter's tragic assassination in November 1963.
Stunned by the loss of Kennedy, the nation rallied around Johnson and elected him to a full,
four-year term in 1964. Johnson, for his part, promised to carry out the policies of the slain
Kennedy.

Johnson, a Texan, had had a long career in politics prior to
becoming president in 1963. A supporter of the New Deal, he became head of the National Youth
Administration in Texas in 1935. He served in both the House of Representatives and the Senate,
before becoming vice president under Kennedy. He was a consummate politician.

Upon becoming president, his domestic agenda was the most ambitious since the New Deal
of the 1930s. His domestic policy was known as the Great Society. Two civil rights acts were
passed. There were also reforms in education and a "war on poverty." Medicare and
Medicaid were enacted.

The Great Society was soon overshadowed by the Vietnam
War, however. America was heavily engaged in Vietnam from 1965 to 1973. The long and expensive
war was supposed to halt the spread of Communism, but it was a costly and bloody failure. The
United States wasted billions fighting an unwinnable war, and the unpopularity of the conflict
severely damaged Johnson's reputation.
