After the 2010 census Alabama redrew its voting map with the result that some districts became more white/Republican and others more black/Democratic. Two groups, the Alabama Legislative Black Caucus and the Alabama Democratic Conference challenged the state’s redistricting plan saying that the plan “packed” predominantly African American districts on the basis of race.
It’s a complicated and unusual case where the sides historically arguing racial quotas have switched. Rather than attempt to explain the argument, I’ll just post my pictures and refer the reader to Richard Hansen’s analysis on SCOTUSblog.
” . . the so-called “crab claws” that the parties describe that extend out from the district capture African American populations.” -Solicitor General Verrilli
