• IN THE UNITED STATES COURT OF APPEALS FOR THE FIFTH CIRCUIT No. 87-3463 RONALD CHISOM, et al., • Plaintiffs-Appellants, v. • EDWIN EDWARDS, et al., Defendants-Appellees. AFFIDAVIT OF DR. RICHARD L. ENGSTROM Richard L. Engstrom, being sworn, deposes and says: 1. I make this affidavit in support of Appellants' Motion for an Injunction Pending Appeals or, in the Alternative, for Issuance of the Mandate. 2. I am currently Research Professor of Political Science at the University of New Orleans, in New Orleans, Louisiana. A copy of my current curriculum vitae is attached to this affidavit as Appendix A. 3. I have done extensive research into the relationship between electoral structures and the ability of black voters to participate fully in the political process and to elect the candidates of their choice. Among my many publications are Engstrom & Wildgen, Pruning Thorns From the Thicket: An Empirical Test of the Existence of Racial Gerrymandering, 2 Legis. Stud. Q. 465 (1977); Engstrom & McDonald, Quantitative Evidence in Vote Dilution Litigation: Political Participation and Polarized Voting, 17 Urb. Law. 369 (1985); and Engstrom, The Reincarnation of the Intent Standard: Federal Judges and At-Large Election Cases, 28 How. L.J. 495 (1985). Each of these was cited with approval in Thornburg V. Gingles, 478 U.S. , 92 L.Ed.2d 25 (1986), the only Supreme Court decision interpreting amended section 2 of the Voting Rights Act. See, e.g., 92 L.Ed.2d at 48, n. 20, 50, 60. 4. I was retained by the plaintiffs in Clark v. Edwards, No. 86-435-A (M.D. La.), to analyze several issues with regard to the opportunities of black voters in Louisiana to participate in the judicial elections process and to elect the candidates of their choice. Among other things, I was asked to examine the results of judicial elections in which black candidates ran to determine whether such elections are racially polarized, that is, whether there is "a correlation between the race of voters and the selection of certain candidates." Thornburg v. Gingles, 92 L.Ed.2d at 61. 5. Appellants in this case have asked me to present my findings with regard to the presence of racial polarization in judicial elections conducted within Orleans Parish. 6. I used two complementary methods for determining whether voting was racially polarized--extreme case (or homogeneous precinct) analysis and bivariate ecological regression. These are the methods approved by the Supreme Court in Gingles. 92 L.Ed.2d at 48. A brief summary of the methodology is contained in Appendix B. 2 7. There were 27 separate contests in which Black candidates ran against white opponents. ( In four of those contests, two black candidates competed.) Regression analyses of these elections show that black voters cast a majority of their votes for the black candidates in 24 of the 27 elections. By contrast, white voters preferred white candidates in all 27 contests. The estimates based on extreme case analysis show the same pattern: in 24 of the 27 elections a majority of black voters voted for black candidates, while in all 27 elections a majority of white voters voted for white candidates. The estimated racial divisions in the vote revealed by the regression analyses of these elections, along with the correlation coefficient reflecting the consistency with which the race of the registered voters in the various precincts is associated with the vote for the respective black candidates, are reported in Appendix C, Table 1 and Table 3. The estimated racial divisions in the vote revealed by the extreme case analyses are reported in Appendix C, Table 2 and Table 4. 8. I conclude from my analysis that voting within Orleans Parish in judicial elections reflects racial polarization, as that term is defined in les.

Reported in the tables are simply the percentage of the votes cast within each group of homogeneous precincts (black or white) that were cast in support of the black candidate. Bivariate Ecological Regression Bivariate ecological regression provides estimates of the same behavior, but employs data for all precincts, not just those that are racially homogeneous. The figures reported in the tables are based on the empirical relationship between the percentage of registered voters in every precinct and (1) the percentage of registered voters in every precinct voting for the black candidate(s) and (2) the percentage voting for white candidate(s). By examining two summary statistics through which these empirical relationships are expressed -- the intercept and the regression coefficient -- it is possible to estimate the percentage of both white and black registered voters who voted in a particular election, and also the percentage of the votes cast by each racial group that were cast in favor of a particular candidate. Each analysis has been weighted to reflect the different number of registered voters within each precinct. For a more detailed explanation of this estimation procedure (which was employed by the plaintiffs' expert witness in the Gingles case), see Grofman, Migalski, and Noviello, "The Totality of Circumstances Test" in Section 2 of the 1982 Extension of the Voting Rights Act: A Social Science Perspective, 7 Law and Policy 119, 202-205 (1985) (cited in Thornburg V.
