Good!
The whole idea of modern racial gerrymandering (as promoted by Richard M. Nixon) has been to isolate black voters in electoral "cancer wards" where hypermajorities are concentrated to eyeball-popping levels, but surrounding districts are likewise spared their democracy-busting, staight-ticket-Democratic voting patterns.
If all the black racist (since the author is calling people racists today) voters in Sheila Jackson Lee's old Houston district (which 40 years ago elected George H. W. Bush to the House, before the Democrats redrew it especially and specifically for Barbara Jordan) , as it was, say, 16 years ago, were redistributed among three or four districts, the Texas House GOP Caucus might be down two or three members.
Something to think about. And it was exactly what Dick Nixon was thinking about when he promoted "minority-majority" redistricting, to "de-blacken" as many U. S. House districts as possible nationwide, to take the pressure off Republican candidates (since black voters generally hate Republicans and vote against them 9:1 or 8:1; even educated blacks vote against them by 2:1 or 3:1).
