During his presidency, his agenda for Congress was to pass his "Great Society" programs, wide-ranging initiatives on health and health care, education, conservation, urban renewal, etc. The Medicare and Medicaid programs were initiated. He was known for supporting civil rights and public broadcasting. The Voting Rights act was passed during his presidency, as was the Civil Rights Act of 1968. Under his administration the U.S. space program continued its pursuit of the challenge President Kennedy had laid down to place an American on the moon before the end of the 1960s, a goal that was realized on July 20, 1969, a few months after Johnson left office. However, his inability to end the conflict in Vietnam cast a pallor on his term and led to widespread anti-war demonstrations, and he chose not to run for re-election in 1968. Lyndon Johnson died in 1973.
