The measure of its historic nature can also be taken by the number of presidents who have tried and failed to get health care passed, from its listing in the Progressive Party platform in 1912 under the heading of social and industrial justice, to FDR's failed attempt to include it in Social Security, from Truman's fight for it, to LBJ's signing of Medicare in the presence of Truman, from Nixon to Clinton.
