Why It Matters
South Carolina’s congressional map is poised for a significant redraw that could reshape the state’s political landscape ahead of the midterm elections. The expected new boundaries would eliminate the state’s only majority-minority district, currently held by Democratic Rep. James Clyburn — one of the most influential Democrats in Congress.
The move places South Carolina at the center of a broader national push by Republican-led states to redraw district lines following a period of sustained turbulence over political cartography in the state and across the South.
What Happened
South Carolina Gov. Henry McMaster on Thursday issued an executive order calling the state General Assembly back for a special session to address both the state budget and congressional redistricting. McMaster announced the session would begin Friday morning.
“I have issued an Executive Order calling the General Assembly back for an extra legislative session to address the state budget and congressional districts,” McMaster posted on X Thursday evening.
The move came after the Republican-led state Senate declined earlier this week to extend its regular session to take up redistricting. Five Republican senators — including Senate Majority Leader Shane Massey — withheld the two-thirds vote required under standard session rules to advance a new map.
Massey explained his position in a floor speech, saying the Republican Party benefits from having a competitive opposition. “Republicans are stronger when the Democrat Party is vibrant and viable,” he said.
In a special session, however, only a simple majority in each chamber is required — a lower threshold that makes passage of a new map significantly more achievable.
Trump Pressure and Party Reluctance
President Donald Trump had publicly urged South Carolina Republicans earlier this week to join what he framed as a national Republican redistricting effort. In a post on Truth Social, Trump called on the state’s lawmakers to act boldly, invoking Tennessee’s recent map changes as a model.
McMaster had initially declined to call a special session, but reversed course after the Senate’s procedural defeat and continued pressure from the White House and national Republicans.
By the Numbers
- 1 — South Carolina’s current number of majority-minority congressional districts, held by Rep. James Clyburn
- 5 — Republican state senators who blocked the two-thirds threshold needed to extend the regular legislative session for redistricting
- Simple majority — the vote threshold now required in each chamber during the special session to pass a new map, down from two-thirds under the regular session rules
- 4+ — Southern states, including South Carolina, Tennessee, Alabama, and Louisiana, simultaneously pursuing mid-decade redistricting changes
Zoom Out
South Carolina’s special session is part of a coordinated wave of redistricting activity across the South, accelerated by a recent U.S. Supreme Court ruling that curtailed Voting Rights Act protections against racial gerrymandering. Since that decision, multiple states have moved swiftly to redraw maps.
Tennessee enacted a new congressional map that divided its only majority-Black district, represented by Rep. Steve Cohen. Alabama received Supreme Court clearance to implement a map reducing its majority-minority districts. Louisiana’s state Senate passed a map this week that targets one of two Democratic-held seats in that state.
The coordinated nature of the effort reflects a strategic Republican push to expand the party’s House majority before the midterms, with the Supreme Court’s ruling providing legal cover that had not previously existed.
What’s Next
The South Carolina General Assembly was set to convene in special session beginning Friday. With a simple majority now sufficient to adopt new district lines, Republican leaders are expected to have the votes to advance a redrawn map. If passed, the new boundaries would likely take effect before the next congressional primary cycle.
Clyburn, a longtime Democratic power broker who has represented his district for decades, would face a substantially altered constituency under the anticipated map. Legal challenges to the new boundaries are widely expected given the ongoing national litigation over post-ruling redistricting efforts.
South Carolina’s redistricting fight underscores the high stakes of a political and legal environment that has been in flux since the Supreme Court’s ruling reshaped the rules of the map-drawing process across the country.
