Among its national spokesmen, although not the best known, was Thomas Ewing, Jr., a noted Free State advocate in Kansas before the civil war, a controversial major general of Union forces during the war, and a Republican turned Democrat after the Grant Administration. His national debates on Greenback monetary policy led the party's growth and influence as spokesmen against the post-war redevelopment of monopolistic gold-based capitalism. Ewing's advice to Andrew Johnson had helped point the administration towards an anti-gold-standard Treasury department.
