This is true. Southern DINOs would not go near the GOP, because of Lincoln and the "war of northern aggression". Saint Reagan turned them to the GOP with racist dog whistles.

It was actually Nixon with the Southern Strategy that began the migration of the Southern racists to the GOP.

"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.[a] 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.[7] By winning all of the South, a presidential candidate could obtain the presidency with minimal support elsewhere.[8][9]

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.[10] 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,[11][12] though several aspects of this view have been debated by historians and political scientists.[13][14][15][16][17]

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.[7] In 2005, Republican National Committee chairman Ken Mehlman formally apologized to the National Association for the Advancement of Colored People (NAACP) for exploiting racial polarization to win elections and for ignoring the black vote.[18][19]"
