"This made up myth about the parties switching because of the CRA is completely bogus."

The USA's two major parties had previously flipped alignment every 70 years. We're overdue.

Contemporaries conflate liberal / conservative, left / right, Democrat / Republican (nee Whig). A less wrong mental model is that parties are coalitions.

LBJ understood this and correctly predicted that CRA would result in the white supremacists switching from Democrat to Republican.

The big political science mystery now is why each party's coalition has become more homogeneous. Where a voter's position on one issue (abortion) is a very strong predictor for many other issues (climate crisis). Stated another way, the need for an explanation for why so many policy issues have become partisan issues.

PS- It is distressing that you dispute the claims of the actual players involved. If you don't trust the first hand accounts, who do you trust? https://en.wikipedia.org/wiki/Southern_strategy#Roots_(1963%...
