1928, when the Democratic candidate was Al Smith, a Catholic New Yorker; and even in that election, the divided South provided Smith with nearly three-fourths of his electoral votes. Scholar Richard Valelly credited Woodrow Wilson's 1912 election to the disfranchisement of black people in the South, and also noted far-reaching effects in Congress, where the Democratic South gained "about 25 extra seats in Congress for each decade between 1903 and 1953". In the Deep South (South Carolina, Georgia, Alabama, Mississippi, and Louisiana), Democratic dominance was overwhelming, with Democrats routinely receiving 80%–90% of the vote, and only a tiny number of Republicans holding state legislative seats or local offices. Mississippi and South Carolina were the most extreme cases – between 1900 and 1944, only in 1928, when the three subcoastal Mississippi counties of Pearl River, Stone and George went for Hoover, did the Democrats lose even one of these two states' counties in any presidential election. In the remaining states, the German-American Texas counties of Gillespie and Kendall, and a number of counties in Appalachian parts of Alabama and Georgia, would vote Republican in presidential elections through this period. In the Upper South (Tennessee, North Carolina, Arkansas, and Virginia), Republicans retained a significant presence mainly in these remote Appalachian and Ozark regions which supported the Union during the Civil War, even winning occasional governorships and often drawing over 40% in presidential votes. By the 1920s, as memories of the Civil War faded, the Solid South cracked slightly. For instance, a Republican was elected U.S. Representative from Texas in 1920, serving until 1932. The Republican national landslides in 1920 and 1928 had some effects. In the 1920 elections, Tennessee elected a Republican governor and five out of 10 Republican U.S. Representatives, and became the first former Confederate state to vote for a Republican candidate for U.S. President since Reconstruction. However, with the Democratic national landslide of 1932, the South again became solidly Democratic. In the 1930s, black voters outside the South largely switched to the Democrats, and other groups with an interest in civil rights (notably Jews, Catholics, and academic intellectuals) became more powerful in the party. This led to the national Democrats adopting a civil rights plank in 1948. In response, a faction of Deep South Democrats ran their own segregationist "Dixiecrat" presidential ticket, which carried four states: South Carolina, Alabama, Mississippi, and Louisiana. Even before then, a number of conservative
