The Washington Post previews redistricting in Georgia.  It presents a scenario which could be permissible under Section 5 of the Voting Rights Act, or else might implicate Section 2 of the Voting Rights Act: Combining John Barrow and Sanford Bishop into the same district by creating a new majority black district.  Currently Barrow and Bishop are not in majority black districts. 

Moreover, Georgia will gain an additional Congressional seat that will likely be used to create another GOP Congressional district in the suburbs north of Atlanta.  Combining Bishop and Barrow to create a new majority minority district would allow the more republican leaning portions of their old districts to be distributed to other GOP districts. 

This is an example where the midterm tsunami of 2010 has implications far beyond who won or lost the elections.
