  1. Isnt much of this explained by population density? So places where cotton was grown in the late 1800s have higher population density today, that would explain most of this..

  2. Could it be that places where cotton was grown had higher black population and that is still the case today?…and we all know for whom African Americans voted….

  3. This is the so-called “Black belt” (i.e., high concentrations of African-American voters). You can see results like this stretching back many elections. And take a look at county-level results of this year’s Senate elections in MS, AL, GA, and SC. Same exact pattern.
