In American politics, the Southern strategy was a Republican Party electoral strategy to increase political support among white voters in the South by appealing to racism against African Americans. As the civil rights movement and dismantling of Jim Crow laws in the 1950s and 1960s visibly deepened existing racial tensions in much of the Southern United States, Republican politicians such as presidential candidates Richard Nixon and Barry Goldwater developed strategies that successfully contributed to the political realignment of many white, conservative voters in the South who had traditionally supported the Democratic Party so consistently that the voting pattern was named the Solid South. The strategy also helped to push the Republican Party much more to the right. By winning all of the South, a presidential candidate could obtain the presidency with minimal support elsewhere.

The phrase "Southern strategy" refers primarily to "top down" narratives of the political realignment of the South which suggest that Republican leaders consciously appealed to many white Southerners' racial grievances to gain their support. This top-down narrative of the Southern Strategy is generally believed to be the primary force that transformed Southern politics following the civil rights era. The scholarly consensus is that racial conservatism was critical in the post–Civil Rights Act realignment of the Republican and Democratic parties, though several aspects of this view have been debated by historians and political scientists.

The perception that the Republican Party had served as the "vehicle of white supremacy in the South", particularly during the Goldwater campaign and the presidential elections of 1968 and 1972, made it difficult for the Republican Party to win back the support of black voters in the South in later years. In 2005, Republican National Committee chairman Ken Mehlman formally apologized to the National Association for the Advancement of Colored People (NAACP) on behalf of the party for its historical exploitation of racial polarization to win elections and for ignoring the black vote.

Introduction Although the phrase "Southern Strategy" is often attributed to Nixon's political strategist Kevin Phillips, he did not originate it but popularized it. passim In an interview included in a 1970 New York Times article, Phillips stated his analysis based on studies of ethnic voting:

While Phillips sought to increase Republican power by polarizing ethnic voting in general, and not just to win the white South, the South was by far the biggest prize yielded by his approach. Its success began at the presidential level. Gradually, Southern voters began to elect Republicans to Congress and finally to statewide and local offices, particularly as some legacy segregationist Democrats, such as Strom Thurmond, retired or switched to the GOP. In addition, the Republican Party worked for years to develop grassroots political organizations across the South, supporting candidates for local school boards and city and county offices as examples, but following the Watergate scandal Southern voters came out in support for the "favorite son" candidate, Southern Democrat Jimmy Carter.

From 1948 to 1984, the Southern states, for decades a stronghold for the Democrats, became key swing states, providing the popular vote margins in the 1960, 1968 and 1976 elections. During this era, several Republican candidates expressed support for states' rights, a reversal of the position held by Republicans since the Civil War. Some political analysts said this term was used in the 20th century as a "code word" to represent opposition to federal enforcement of civil rights for blacks and to federal intervention on their behalf; many individual southerners had opposed passage of the Voting Rights Act.

Background Reconstruction to Solid South

During Reconstruction, the Republican Party built up its base across the South and controlled each state except Virginia, but from a national perspective, the Republicans gave priority to its much better established Northern state operations. Southerners distrusted the scalawags, found the carpetbaggers distasteful, and lacked respect for the black component of their Republican Party in the South. Richard Abbott says that national Republicans always "stressed building their Northern base rather than extending their party into the South, and whenever the Northern and Southern needs conflicted the latter always lost".Richard H. Abbott, The Republican Party and the South, 1855–1877: The First Southern Strategy (1986) p. 231 In 1868, the GOP spent only 5% of its war chest in the South. Ulysses S. Grant was reelected and the New York Tribune advised it was now time for Southern Republicans to "root, hog, or die!" (that is, to take care of themselves).

During the 1876 United States presidential election, the Republican ticket of Rutherford B. Hayes and William A. Wheeler (later known as members of the comparably liberal "Half-Breed" faction) abandoned the party's pro-civil rights efforts of Reconstruction and made conciliatory tones to the South in the form of appeals to old Southern Whigs.About the Vice President|William A.

In a series of compromises, such as the Compromise of 1877, the Republicans withdrew military forces that had propped up their last three state governors and in return gained the presidency for Hayes.C. Vann Woodward, Reunion and Reaction: The Compromise of 1877 and the End of Reconstruction(1956) pp. 8, 205–12 All the southern states were now under the control of the Democrats, who increased their control of virtually all aspects of politics in the ex-Confederate states during the ensuing decades. There were occasional pockets of Republican control, but they were usually in remote mountain districts.Vincent P. De Santis, Republicans face the southern question: The new departure years, 1877–1897 (1959) pp. 71–85

After 1890, the white Democrats used a variety of tactics to reduce voting by African Americans and poor whites.Nicholas Lemann, Redemption: The Last Battle of the Civil War (New York: Farrar Straus & Giroux, 2007), pp. 74–80 The rise of primaries in the electoral system allowed for the 15th Amendment to be circumvented using a white primary. Winning the Democratic primary was tantamount to winning the election during the period of the solid south. From 1890 to 1908, the white Democratic legislatures in every Southern state enacted new constitutions or amendments with provisions to disenfranchise most blacks and tens of thousands of poor whites. Provisions required payment of poll taxes, complicated residency, literacy tests and other requirements which were subjectively applied against blacks. As blacks lost their vote, the Republican Party lost its ability to effectively compete in the South. pp. 1–8

Because blacks were closed out of elected offices, the South's congressional delegations and state governments were dominated by white Democrats until the 1980s or later. Effectively, Southern white Democrats controlled all the votes of the expanded population by which congressional apportionment was figured. Many of their representatives achieved powerful positions of seniority in Congress, giving them control of chairmanships of significant congressional committees. Although the Fourteenth Amendment has a provision to reduce the congressional representation of states that denied votes to their adult male citizens, this provision was never enforced. As African Americans could not be voters, they were also prevented from being jurors and serving in local offices. Services and institutions for them in the segregated South were chronically underfunded by state and local governments, from which they were excluded."Beginnings of black education" , The Civil Rights Movement in Virginia.

Republicans rarely held seats in the U.S. House from the South during the Solid South period with the party only holding two seats in Tennessee between 1947 and 1952, out of the 105 seats in the south. Republicans won 80 of 2,565 congressional elections in the south during the first half of the 20th century. Between 1902 and 1950, all US Senators from the south were Democrats. Republicans held around 3% of state legislative seats in the south in 1948, and held zero seats in five states.

Between 1880 and 1904, Republican presidential candidates in the South received 35–40% of that section's vote (except in 1892, when the 16% for the Populists lowered Republicans down to 25%). From 1904 to 1948, Republicans received more than 30% of the section's votes only in the 1920 (35.2%, carrying Tennessee) and 1928 elections (47.7%, carrying five states) after disenfranchisement.

During this period, Republican administrations appointed blacks to political positions. Republicans regularly supported anti-lynching bills, but these were filibustered by Southern Democrats in the Senate. In the 1928 election, the Republican candidate Herbert Hoover rode the issues of prohibition and anti-Catholicism to carry five former Confederate states, with 62 of the 126 electoral votes of the section. After his victory, Hoover attempted to build up the Republican Party of the South, transferring his limited patronage away from blacks and toward the same kind of white Protestant businessmen who made up the core of the Northern Republican Party. With the onset of the Great Depression, which severely affected the South, Hoover soon became extremely unpopular. The gains of the Republican Party in the South were lost. In the 1932 election, Hoover received only 18.1% of the Southern vote for re-election.

From 1860 and 1930, the Republicans controlled the U.S. Senate in thirty-one of thirty-six sessions and the U.S. House in twenty-three sessions. Between 1932 and 1992, the Republicans controlled the U.S. Senate for five out of thirty-one sessions and the U.S. House for two sessions.

Internal Republican politics According to Boris Heersink and Jeffery A. Jenkins, blacks did have a voice in the Republican Party, especially in the choice of presidential candidates at the national convention. They argue that in 1880–1928 Republican leaders at the presidential level adopted a "Southern Strategy" by "investing heavily in maintaining a minor party organization in the South as a way to create a reliable voting base at conventions", causing federal patronage to go to Southern blacks as long as there was a Republican in the White House.Boris Heersink and Jeffery A.

Southern states sent delegations to Republican conventions that accounted for one-fourth of the overall number despite the Democratic dominance of the region. These delegates were viewed as rotten boroughs and gave their support to the incumbent or the frontrunner. Mark Hanna started to lobby southern Republicans in favor of William McKinley in 1895, and McKinley came to the 1896 Republican National Convention with control of all of the southern delegations, which accounted for almost half of the votes required to win, except for Texas. The issue of southern delegates exploded in 1912, when William Howard Taft used his 83% control of Southern delegations to defeat Theodore Roosevelt at the convention. Delegate allocation by state was altered after this election to be based on how well the party did electorally in those states. Southern delegate sizes fell from 23% of the total delegates in 1912, to 18% in 1916.
