In point of fact, of the 77 members of the 84th U.S. Congress who were non-signatories to the 1956 Southern Manifesto from the 17 former Confederate and border states where racial segregation of public schools was legally required prior to the 1954 "Brown v. Board of Education" Supreme Court case, 65 non-signatories were from the states Trende identifies as part of the "Greater Appalachia" region (West Virginia, Kentucky, Tennessee, Missouri, Oklahoma, and Texas). Likewise, 31 of the 42 Southern votes in favor of the Civil Rights Act of 1957, 46 of the 58 Southern votes in favor of the Civil Rights Act of 1960, 29 of the 41 Southern votes in favor of the Civil Rights Act of 1964, 48 of the 70 Southern votes in favor of the Voting Rights Act of 1965, 11 of the 15 Southern votes in favor of the confirmation of Thurgood Marshall to the U.S. Supreme Court, and 46 of the 65 Southern votes in favor of the Civil Rights Act of 1968 came from U.S. Senators and U.S. House Representatives representing states from Trende's "Greater Appalachia."
