The document discusses Lyndon B. Johnson's presidency, including his background as a congressional staffer, representative, senator and vice president. As president, LBJ declared a War on Poverty and enacted major civil rights legislation like the Civil Rights Act of 1964 and Voting Rights Act of 1965. However, his expansion of US involvement in the Vietnam War and the 1968 Tet Offensive weakened his support and led him to decide not to run for re-election.
