Kinda sucks how SC-03 is the one South Carolina seat that's truly uber-safe R under any circumstances; Trump won the current config by 37.5%; every other seat is less than Trump + 20. Dems probably wouldn't win SC-04 but they could still could be an interesting race.
I've theorycrafted a scenario where I somehow win in a 2027 special election, but it's pretty outlandishly unrealistic, requiring a moderate conservative split and the R candidate to be a local crazy who has an absolute treasure trove of statements that are radical even for the area, talking about the civil rights movement being "communistic" etc.
Yeah, that candidate would likely be too busy serving as Lt Gov to offer a serious challenge.
