In Alabama, I'd imagine things would be similar, with the northwestern and northeastern counties supporting secession while losing heavily in the urban and central counties. Yes's best county would be without a doubt Lauderdale, while No's best would probably be Macon. In Arkansas, where I'm moving to soon, Yes's best would likely be Boone County, while No's best would most likely be Pulaski (where Little Rock is) or Chicot County. Arkansas's pattern would be basically the same, with Yes performing best in Rural northwestern and especially well in places in southern Arkansas with high concentrations of whites, while doing terrible in urban and African American counties. Unfortunately, I'm using a Mac, so I can't use MS Paint to draw all of this out.
First off, where in Arkansas are you moving to, I could meet up with you if you're moving near me. Second, I would expect the vote to play out like this.
Here is the Statewide vote for no on our Gay marriage ban.
Counties which have a >10 would have the highest yes vote, but it shouldn't pass in any county.
