South Carolina should be a state where redistricting is straightforward, much like what unfolded in Florida. The Supreme Court’s decision in Louisiana v. Callais effectively narrowed the practical reach of Section II of the Voting Rights Act, weakening the use of race as the driving force behind congressional mapmaking. Across the South, states are now moving to redraw districts with far fewer legal restraints than existed just a few years ago. Florida completed the process in a matter of days. Tennessee moved quickly. Alabama just received a green light from the Supreme Court. Which raises an obvious question: why is South Carolina still stalled?
The answer comes down to one thing: resistance inside the South Carolina Republican establishment.
More specifically, the roadblock sits in the South Carolina Senate. Republicans hold 34 of the chamber’s 46 seats, yet a small bloc of GOP senators has slowed the push to redraw the state’s congressional map and potentially dismantle Democrat Rep. James Clyburn’s district.

According to reporting from the Charleston City Paper, momentum appeared dead earlier this week after Gov. Henry McMaster announced he would not call lawmakers back for a special session focused on redistricting. McMaster pointed to logistical concerns, noting that statewide primary elections are scheduled for June 9 and that military and overseas ballots had already been mailed.
But pressure from President Donald Trump and grassroots Republican activists reignited the effort almost immediately.
On Wednesday, South Carolina House Republicans pushed forward anyway, passing a resolution authorizing a special session by an 87-25 party-line vote. The House signaled it was ready to move aggressively. The Senate, however, remains divided.
At the center of the resistance is Senate Majority Leader Shane Massey, who openly warned against pursuing a 7-0 Republican congressional delegation.
“I think if you try to get 7-0, you’re more likely to get 5-2,” Massey said. “Trying to get cute with this is more likely to cause a problem than be beneficial.”
That argument has not gone over well with activists who see neighboring Southern states acting decisively while South Carolina hesitates despite holding overwhelming Republican majorities statewide.
4 of these have moved to firm YES and 4 are still on the fence.

The political math inside the Senate has shifted rapidly over the last 48 hours. Of the nine Republican holdouts initially resisting the plan, four have reportedly flipped in favor, while another four are now undecided. Massey remains firmly opposed.
For many conservatives pushing the effort, the situation increasingly resembles other Republican intraparty fights over redistricting strategy. Indiana became a cautionary tale after several anti-redistricting Republicans were defeated in primaries following backlash from the party base.
