Long-term volunteers staffed the COFO and SNCC offices throughout Mississippi . After the flood of summer workers in 1964 , their leadership decided that projects should continue the following summer , but under the direction of local leadership . This was challenged by Northern establishment members of the coalition , beginning with Americans for Democratic Action , who also disapproved of the MFDP . This encouraged the NAACP to withdraw from COFO , both because they did not want to anger liberal Democrats , and because they resented the organizational competition from SNCC . After the MFDP was denied voting status at the 1964 Democratic National Convention , Bob Moses was deeply disillusioned and bowed out of both MFDP and COFO . COFO collapsed in 1965 , leaving organizing priorities to be set by locals
