The focus of this dissertation is the political career of R. Vance Hartke, Democratic Senator from Indiana 1958-1976. The areas of emphasis include Hartke's role in the creation of the Veterans' Affairs Committee of the Senate and his chairmanship of the Committee, several of the controversies of his career, and his political style and philosophy.Books and articles written by Hartke were used extensively as were various newspapers and the Conqressional Record. Information was also obtained from interviews with Hartke and Frank Brizzi, who was staff director of the Veterans' Affairs Committee during Hartke's term as chairman.That Hartke philosophically was a liberal and politically was a risk-taker are among the conclusions reached in this study. Hartke's strongest asset in winning election to the Senate three times in a relatively conservative state was an energetic and personalized political style. Despite the controversies which surrounded Hartke and some apparent conflicts of interest," there is no evidence he committed illegal or unethical acts. Hartke used his power as chairman of the Veterans' Affairs Committee of the Senate to infuse his liberal ideology into public policy for American veterans. Furthermore, he expanded veterans' benefits during his tenure. / Department of Political Science
