As you may recall, I preferred drawing a second black-majority CD in SC, which would (i) protect against the possibility of judicial redrawing of the districts, (ii) keep 5 CDs 100% safe for Republicans and (iii) make it extremely difficult for RATs to draw a map that favored Democrats if they gained control of the SC legislature and governorship by 2022 (since it would violate the VRA not to have 2 black-majority CDs once they have been created). But that’s just me: I’m a strong proponent of “safety first” and of packing Democrats whenever possible even at the cost of picking up an extra GOP CD. If we hold a 6-1 delegation for the rest of the decade—and the only seats truly at risk are Mulvaney’s SC-05 and Rice’s SC-07 (the SC-01 and SC-2 are theoretically winnable for Dems, but at 59% for Romney in spite of historic black turnout I’m not too concerned about them), I think that Republicans should go for 6-1 again in 2022 by expanding the black-majority SC-06 (which likely will need to pick up population once again) to take in black precincts in the SC-05 and SC-07, and have the SC-03 and SC-04 take in some more marginal (due to relatively large black population) counties to their south, and thus draw 6 CDs that are a couple of points more Republican than the state as a whole.
The irony that the very election and presence of Tim Scott in SC-1 is proof positive that the VRA should be done away with (ditto Democrat Steven Horsford in the new NV-4). It is nothing but protection for Democrat seats, for which Republicans enjoy no such similar measures (aside from perhaps the Cuban seats in Florida, but that didn’t help us to hold all three).
