At the 1964 Democratic National Convention, which followed Freedom Summer in Mississippi, Rustin became an adviser to the Mississippi Freedom Democratic Party (MFDP); they were trying to gain recognition as the legitimate, non-Jim Crow delegation from their state, where blacks had been officially disenfranchised since the turn of the century (as they were generally throughout the South) and excluded from the official political system. DNC leaders Lyndon Johnson and Hubert Humphrey offered only two non-voting seats to the MFDP, with the official seating going to the regular segregationist Mississippi delegation. Rustin, following a line set by Shachtman and AFL-CIO leaders, urged the MFDP to take the offer. MFDP leaders, including Fannie Lou Hamer and Bob Moses, angrily rejected the arrangement; many of their supporters became highly suspicious of Rustin. Rustin's attempt to compromise appealed to the Democratic Party leadership.
