With partial participation in the regular Mississippi Democratic Party blocked by segregationists , the Council of Federated Organizations ( COFO ) built on the success of the Freedom Ballot by formally establishing the MFDP in April 1964 as a non-discriminatory , non-exclusionary rival to the regular party organization . The MFDP hoped to replace the regulars as the officially recognized Democratic Party organization in Mississippi by winning the Mississippi seats at the 1964 Democratic National Convention for a slate of delegates elected by some black and white Mississippians and white sympathizers
