Out of the 49 House Dems, 10 are white.
Almost the same percentage as in Alabama (is Hughes in LD-12 black or white, BTW?)... Democratic caucus in Southern states becomes almost identical with "Black caucus". The same will happen in Louisiana after 2019, when a lot of white incumbents in House will be term-limited and will be replaced either by Republicans or by black Democrats...
to be clear, it's white Democrats getting replaced by Republicans, almost exclusively. Black districts vote for black Democrats, like they have for fifty years. It's the bulk of white people voting for Republicans instead of Democrats that causes the shift you're talking about
