The election was a seismic event in the long-term realignment in Democratic Party support, especially in the South. Nationwide, the bitter splits over civil rights, the new left, the Vietnam War, and other "culture wars" were slow to heal. Democrats could no longer count on white Southern support for the presidency, as Republicans made major gains in suburban areas and areas filled with Northern migrants. The rural Democratic "courthouse cliques" in the South lost power. While Democrats controlled local and state politics in the South, Republicans usually won the presidential vote. In 1968, Humphrey won less than ten percent of the white Southern vote, with two-thirds of his vote in the region coming from blacks, who now voted in full strength.
