OOC: This still doesn’t change how the generation which turned the South Republican was indeed not Thurmond’s generation; it was the generation afterwards, after the Civil Rights movement. If the shift was due to Civil Rights, the switch would have occurred during the 60’s. But as we got OTL, the South didn’t go solidly Republican until the mid to late 90’s, 30 years after the Civil Rights Act. It’s as I mentioned before, because of social conservatism and economics. Perhaps I misspoke when using the term Supply-side, but the solid south will break because of economic reasons. The southern states were very poor and their economy had not recovered to pre-Civil War levels until the 1900s. As an example, of the 3 richest states in America in 1860, 2 were southern (South Carolina and Lousiana). Mississippi was 5th in 1860, and it was also the poorest state in the nation come 1960. Without the Great Depression, the Solid South will crumble much earlier. The Republicans were starting to make gains in the South, again as shown by Herbert Hoover in 1928. While you claim it’s because of Hoover’s campaigning and Smith being Catholic, the fact remains that such a performance in the South for a Republican would be completely unthinkable under any circumstances in the South post-reconstruction. The Great Depression discredited the Republican party and led to the New Deal giving benefits to many of the poor whites of the South, including those whom where formerly the core of Republican supporters, which set back the Solid South’s demise by a couple of decades. Without the Great Depression and the New Deal, the Solid South will crack much earlier due to economic reasons. The south’s switch toward Republican is much more multifaceted and complex then “all of the southern democrats switched over to the Republicans after the Civil Rights Act of 1964.” Such a statement or viewpoint vastly oversimplifies a complex change which had much more to do with economic reasons and social conservatism than civil rights, as seen in Hoover’s performance in 1928 and the growing popularity of the GOP prior to FDR and the Great Depression, as well as Eisenhower winning several southern states. While you correctly note that they aren’t the Deep South, the fact remains: the South as a whole was starting to shift before Civil Rights.
