The second of a two-part series on the life of Lyndon B. Johnson, this program traced the president's energetic pursuit of the "war on pover ty" and a range of other social programs; charted the country's deepen ing involvement in Vietnam and the process by which Johnson committed progressively more troops and dollars to the conflict; explored the pe rsonal toll on the president as his popularity plummeted, social strif e spread, and the war dragged on; and chronicled his retirement years in Texas, marked by aimlessness and personal neglect.
