Senate battlers on Pure Politics Act. Washington, D.C., Mar 7. At odds on the Senate floor since the inception of The Hatch Act, but good personal friends are Senators Carol Hatch, D. of New Mexico, author of The Act to Purify Politics, and Senator Sherman Minton, Dem., of Indiana. Latest difference to develop was yesterday when Sen. Miller or Arkansas offered an amendment to draw the teeth from the act be allowing federal employes to 'voluntarily' take part in politics. The amendment was intended to be tacked on to a bill to extend the scope of the act to U.S. paid state and city employees. The Indiana senator, Democratic whip on the floor, acted as floor leader for The Miller Amendment, but the bill was defeated by three votes. Today, the two are as good friends as ever, 3-7-40
