Well, if someone is going to bump this ... haha, I have always been fascinated with the development of Black political loyalty. There is seriously hardly any pre-1932 data (convenient, Democrats! Lol, just kidding), and most of the "story" is told through generalization. (FDR won over the Black vote because New Deal, and Goldwater pushed them to GOP for good, that end of story!) I want to know the details of if different geographic areas might have switched from the GOP first, which remained more loyal, what sub-demographics of Blacks switched first, etc.
I haven't read the book myself, but
Farewell to the Party of Lincoln: Black Politics in the Age of FDR, by Louis Harlan, is a work that's very highly regarded and I believe it discusses many of those questions.
