I don't understand why Arkansas doesn't have at least one African-American majority congressional district (probably would be concentrated in the Arkansas Delta) like other southern states. Isn't it under the sway of the Voting Rights Act which mandates that?
Only 4 representatives, just above 15% African-American, and no plausible way to draw an African-American-majority district. It shouldn't be that surprising, considering that Tennessee (about as black as Arkansas) has 9 representatives but only 1 district that is majority African-American. Also, Virginia is almost 20% black, but only 1 of its 11 congressional districts is predominantly African-American.
