Once gerrymandering became normal and acceptable, it ensured blacks would always be on the outside looking in politically (regardless of which party is in power). As some blacks succeed and move to suburbs, those suburbs eventually become absorbed into a gerrymandered dump with a race huckster representing it. Imagine being a squared-away black person with people like Maxine Waters or Sheila Jackson Lee as your representative...
They will never have common ground politically with any non-black representatives; they are elected to panhandle from the constituents of other representatives.
Good comment
