. The 5 Deep South states, along with
Northern Florida, had the strongest swings to Republican nominee
Barry Goldwater. Note that Texas was the home state of Democratic nominee
Lyndon B. Johnson. Political expert
Kevin Phillips states that, "From the end of Reconstruction until 1948, the Deep South Black Belts, where only whites could vote, were the nation's leading Democratic Party bastions." From the late 1870s to the mid-1960s, conservative whites of the Deep South held control of state governments and overwhelmingly identified with and supported the
Democratic Party. The most powerful leaders belonged to the party's moderate-to-conservative wing. The
Republican Party would only control mainly mountain districts in
Southern Appalachia, on the fringe of the Deep South, during the "
Solid South" period. At the turn of the 20th century, all Southern states, starting with Mississippi in 1890, passed new constitutions and other laws that effectively
disenfranchised the great majority of blacks and sometimes many
poor whites as well. Blacks were excluded subsequently from the political system entirely. The white Democratic-dominated state legislatures passed
Jim Crow laws to impose
white supremacy, including caste segregation of public facilities. In politics, the region became known for decades as the "Solid South". While this disenfranchisement was enforced, all of the states in this region were mainly one-party states dominated by white
Southern Democrats. Southern representatives accrued outsized power in the Congress and the national Democratic Party, as they controlled all the seats apportioned to southern states based on total population, but only represented the richer subset of their white populations. In the
1928 presidential election,
Al Smith received serious backlash as a Catholic, but carried all 5 Deep South states, though he nearly lost Alabama. Major demographic changes would ensue in the 20th century. During the two waves of the
Great Migration (1916–1970), a total of six million African Americans left the South for the Northeast, Midwest, and West, to escape the oppression and violence in the South. Beginning with the
Goldwater–Johnson election of 1964, a significant contingent of white conservative voters in the Deep South stopped supporting national Democratic Party candidates and switched to the Republican Party. They still would vote for many Democrats at the state and local level into the 1990s. Political scientist Seth McKee concluded that in the
1964 presidential election, "Once again, the high level of support for
Goldwater in the Deep South, and especially their Black Belt counties, spoke to the enduring significance of white resistance to black progress." White southern voters consistently voted for the Democratic Party for many years to hold onto Jim Crow Laws. Once
Franklin D. Roosevelt came to power
in 1932, the limited southern electorate found itself supporting Democratic candidates who frequently did not share its views. Journalist
Matthew Yglesias argues: Kevin Phillips states that, "Beginning in 1948, however, the white voters of the Black Belts shifted partisan gears and sought to lead the Deep South out of the Democratic Party. Upcountry, pineywoods and bayou voters felt less hostility towards the New Deal and Fair Deal economic and caste policies which agitated the Black Belts, and for another decade, they kept The Deep South in the Democratic presidential column. The Republican Party in the South had been crippled by the disenfranchisement of blacks, and the national party was unable to relieve their past with the South where Reconstruction was negatively viewed. During the
Great Depression and the administration of Democrat
Franklin D. Roosevelt, some
New Deal measures were promoted as intending to aid African Americans across the country and in the poor rural South, as well as poor whites. In the post-
World War II era, Democratic Party presidents and national politicians began to support desegregation and other elements of the
Civil Rights Movement, from President
Harry S. Truman's desegregating the military, to
John F. Kennedy's support for non-violent protests. These efforts culminated in
Lyndon B. Johnson's important work in gaining Congressional approval for the
Civil Rights Act of 1964 and
Voting Rights Act of 1965. Since then, upwards of 90 percent of African Americans in the South have voted for the Democratic Party, including 93 percent for Obama in 2012.
Late 20th century to present Historian
Thomas Sugrue attributes the political and cultural changes, along with the easing of racial tensions, as the reason why Southern voters began to vote for Republican national candidates, in line with their political ideology. Since then, white Deep South voters have tended to vote for Republican candidates in most presidential elections. Times the Democratic Party has won in the Deep South since the late 20th century include: the
1976 election when Georgia native
Jimmy Carter received the Democratic nomination, the
1980 election when Carter won Georgia; the
1992 election when Arkansas native and former governor
Bill Clinton won Georgia, Tennessee, Louisiana, and Arkansas, the
1996 election when the incumbent president Clinton again won Louisiana, Tennessee and Arkansas, and when Georgia was won by
Joe Biden in the
2020 United States presidential election. In 1995, Georgia Republican
Newt Gingrich was elected by representatives of a Republican-dominated House as
Speaker of the House. The incumbent Speaker of the House since
October 2023, Republican
Mike Johnson, is from Louisiana. Since the 1990s the white majority has continued to shift toward Republican candidates at the state and local levels. This trend culminated in 2014 when the Republicans swept every statewide office in the Deep South region
midterm elections. As a result, the Republican party came to control all the state legislatures in the region, as well as all House seats that were not representing
majority-minority districts. Presidential elections in which the Deep South diverged noticeably from the
Upper South occurred in
1928,
1948,
1964,
1968, and, to a lesser extent, in
1952,
1956,
1992, and
2008. Former Arkansas Governor
Mike Huckabee fared well in the Deep South in the
2008 Republican primaries, losing only one state (South Carolina) while running (he had dropped out of the race before the Mississippi primary). Except for Georgia, the Deep South is strongly Republican. Louisiana, Mississippi, Alabama, and South Carolina have voted Republican for president in every presidential election since
2000. Georgia is the most populous and urbanized Deep South state. Georgia is currently considered a
Swing state. In
2020, the state of Georgia was considered a toss-up state hinting at a possible Democratic shift in the area. It ultimately voted Democratic, in favor of Joe Biden. During the 2021 January Senate runoff elections, Georgia also voted for two Democrats,
Jon Ossoff and
Raphael Warnock, with Warnock winning
re-election to a full term the following year. In
2024, Republican
Donald Trump won the state by a 2.2% margin. • Republicans currently hold every Georgia statewide office, its state Supreme Court, and its state legislature. ==States==
