Majority/minority districts are the creation of SCOTUS. As such, they will be inviolate and the racist Clyburn completely safe.
You are right. But this will allow the SC Legislature to make Clyburn's 6th district more compact when then create a new 7th. If the 6th district line moves about 1/2 mile south I will be in 5th district which is about to be represented by Mick Mulvaney who just unseated John Spratt.
If the GOP controlled SC Legislature is in a humorous mood they might make sure that the 6th district no longer includes Clyburn's house. We'll get a Dem but it may not be him. Maybe Alvin Greene will run for Congress.
