you simply divide the current black district into 2, and combine to the other smallest white districts.
To reach this path, district 7 (taking up Birmingham interior, Montgomery area, and the whole of mid-west Alabama...the least populated area of the state, but about 70-percent black)....you’d water-down the black vote in district 7. I’d take a wild guess by any drawing...probably one-vote of the black vote would have to be dropped into the next district.
Some people believe the intent of the challenge is to create a pure-Birmingham-only district...having nothing to do with Selma or the mid-west part of the state.
The problem with this idea is that a lot of the population of Birmingham have drifted off to 20/30 miles outside of the city (they still work there). The city district they imagine simply doesn’t have the population base to support a Birmingham-only district.
If you talked of gerrymandering and then added up the angles of district 7....there’s probably over 300 angles/curves to it. This current design was set-up in 1993, and today....it’s a plus-14 percent deal on Democratic control. Carving anything off...lessens the control.
