After taking office, he won passage of a major tax cut, the Clean Air Act, and the Civil Rights Act of 1964. After the 1964 election, Johnson passed even more sweeping reforms. Though he left office with low approval ratings, polls of historians and political scientists tend to have Johnson ranked as an above-average president. His domestic programs transformed the United States and the role of the federal government, and many of his programs remain in effect today. In April 1964, Johnson proposed the Economic Opportunity Act of 1964, which would create the Office of Economic Opportunity (OEO) to oversee local Community Action Agencies charged with dispensing aid to those in poverty. The act would also create the Job Corps, a work-training program, and AmeriCorps VISTA, a domestic version of the Peace Corps.
