My Alabama gerrymander would gerrymander the hell out of Mobile County. I would remove all the black precincts from the first district and then stretch the district from the white parts of Mobile County along the Florida border to Houston County. I would then combine the swing counties and the black belt, Montgomery with rural AL-07 for a fairly strong majority black district. I would extricate AL-07 from Jefferson county and make a Jefferson County district that should be at least 40% black and that could reelect Artur Davis, a similar black democrat or a moderate white Democrat.
The problem with moving Montgomery out of AL-03 is that it would put that district out of reach for Democrats. I would try to keep any Southern black majority district in the 50%-54% range to ensure that their votes are not wasted.
