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.
