I think that's part of it, but I do think satisfying some of the major demands dissolved the broad coalition; moderate liberals, especially white liberals, were largely satisfied by the civil-rights legislation, and dropped out of the movement, leaving a much smaller activist core. The SNCC took a huge nosedive in membership after 1965, for example, and even MLK found it harder to muster the same levels of support for his post-'65 causes (like desegregating Chicago, and ending poverty).
