Despite a mixed record of legislative success, the Fair Deal remains significant in establishing the call for universal health care as a rallying cry for the Democratic Party. Lyndon B. Johnson credited Truman's unfulfilled program as influencing Great Society measures such as Medicare that Johnson successfully enacted during the 1960s. The Fair Deal faced much opposition from the many conservative politicians who wanted a reduced role of the federal government. The series of domestic reforms was a major push to transform the United States from a wartime economy to a peacetime economy. In a context of postwar reconstruction and entering the era of the Cold war, the Fair Deal sought to preserve and extend the liberal tradition of President Franklin Delano Roosevelt's New Deal. During this post-WWII time, people were growing more conservative as they were ready to enjoy the prosperity not seen since before The Great Depression. The Fair Deal faced opposition by a coalition of conservative Republicans and predominantly southern conservative Democrats. However, despite strong opposition, there were elements of Truman's agenda that did win congressional approval, such as the public housing subsidies cosponsored by Republican Robert A. Taft under the 1949 National Housing Act, which funded slum clearance and the construction of 810,000 units of low-income housing over a period of six years.
