³ A complete list of sources used to obtain county frequencies for the independent variables used in this analysis is too lengthy to reproduce here. A mimeographed list will be supplied by the authors upon request.

We are indebted to the following research assistants for their help in collecting these data: Lawton Bennett, Lewis Bowman, Barbara Bright, Jack Fleer, Donald Freeman, Douglas Gatlin, and Richard Sutton. All told, the collection and coding of these data took one man-year of work.

⁴ The 1958 registration data contained in the 1959 Report of the Commission on Civil Rights are more complete than the 1960 registration data contained in the Commission's 1961 Report (Washington, 1961), Vol. I, “Voting,” and were used in all states except Tennessee, for which 1958 data were not available.

There are 1136 counties in the 11 southern states (counting Virginia's independent cities as “counties”), of which 1028 had populations containing at least 1 per cent Negroes in 1950. Negro registration figures are not available for 31 of these.

¹⁶ Primary election returns were compiled from Scammon, Richard M. (ed.), Southern Primaries ′58 (Washington, Governmental Affairs Institute, 1959)Google Scholar; from various issues of the Congressional Quarterly Almanac, and Congressional Quarterly Weekly Report; legislative manuals and Reports of Secretaries of State; and the New York Times. Contests involving incumbents in Arkansas and Texas—the only southern states in which governors may succeed themselves—and uncontested races were omitted in computing medians.

¹⁷ The above is not intended to imply a single direction of causality: a meaningful choice may lead more Negroes to register, the registration of more Negroes may lead candidates to take positions more favorable to Negroes, or both. So far as bifactional as opposed to unifactional or multi-factional politics is concerned, however, one can conceive of the pattern of factionalism as the independent variable associated with Negro registration but one can hardly imagine the registration rates of Negroes as the independent variable.

¹⁸ The New York Times was consulted from January, 1945, to February, 1961, and the Southern Educational Reporting Service's “Facts on Film,” Rolls 1-40, first supplement Rolls 1-3, second supplement Rolls 1-11, were examined in a search of news about these organizations. Letters of inquiry were addressed to known national and statewide organizations seeking the location of their local chapters. Persons known to be knowledgeable about the racial politics of specific states and localities also were contacted.

²⁴ These variations are, of course, also the result of chance factors and of the fact that the 21 social and economic variables do not reflect all of the complex social and economic realities of the world. Moreover, the 21 measures we did employ were not themselves perfect measures of the variables they represented.

²⁵ These 10 political variables are (1) states; (2) per cent of presidential vote States' Rights, 1948; per cent of presidential vote Republican (3) in 1928, (4) in 1948 and (5) in 1956; (6) per cent of vote Republican in race for statewide office in year of highest Republican vote, 1950-59; (7) presence or absence of Negro race organization in county; (8) presence or absence of white race organization in county; (9) presence or absence of desegregated school in county; and (10) number of incidents of racial violence in county.
