By the fall of 1963, the Mississippi Freedom Democratic Party (MFDP) had come together (in part as a result of the efforts of COFO) and sought to attend the Democratic National Convention of 1964, which was to be held in Atlantic City, New Jersey. Frustrated by the unwillingness of Mississippi's traditional Democratic Party to fairly and adequately represent all of the state's residents (who were mostly black), the MFDP wanted to challenge the 'Regulars' at the convention for three reasons Poll tax reciept from 1964 : 1) the systematic exclusion of blacks from equal participation in state politics, 2) the disloyalty of the Mississippi Democrats to the national party, and 3) Mississippi's willingness to uphold the unequal, unfair status quo.
