The North Florida District the article mentions at one time was represented by Corrine Brown who ended up in prison. She was a clone of Shiela Jackson-Lee except dumber.
Originally the district covered parts of Jacksonville all the way down to Orlando and in some places the district was divided by a railroad track, a completely gerrymandered district that was specifically designed to elect a black American, the district is now gone.
Actually, that district was changed a few years ago to include my rural north Florida county in a district that went from west Jacksonville across several small, red counties to Tallahassee. Al Lawson from Tallahassee was our rep, a step up from Corinne but still reliably Dem. Now our new district is represented by the wonderful Kat Cammack and I sure hope it stays that way!
