Along with Curtis Gans in 1967 , and later that fall joined by Wisconsin 's Midge Miller , Lowenstein started the " Dump Johnson " movement , approaching Senators Robert F. Kennedy and , at Kennedy 's suggestion , George McGovern about challenging President Johnson in the 1968 Democratic primaries . When Kennedy and McGovern both declined , Lowenstein , a delegate to the Democratic National Convention , recruited and worked for Eugene McCarthy , to whose candidacy he remained loyal , even after Kennedy 's late entry into the race ( before Johnson bowed out ) . Johnson 's withdrawal from the presidential nomination process has been attributed to the impact of the " Dump Johnson " movement , culminating in the historical precedent of McCarthy 's strong showing against Johnson in the New Hampshire primary
