"Sawz...why are you demanding that someone provide YOU with detailed research in order to make a general point about change in politics?"

Because the Dixiecrat argument is a myth. That's why nobody can come up with any details. You want me to prove your myth?

I found that list previously and it shows members of "The Dixiecrat Party largely dissolved after the 1948 election." Not the "large number" that became Republicans.

And what happened in 1952 that has any bearing on what is happening now?
