Was Georgia HD12 McKinney's old turf?
No, it's the heavily black district from Augusta to Savannah that Max Burns won in 2002 but lost to John Barrow in 2004; the GOP legislature redistricted last year and the district no longer includes Barrow's home base in Athens.
No. GA-12 is Eastern Georgia, including, I believe, Augusta -- but excluding Savannah and the coast.
