South Carolina’s push to reshape its congressional districts moved into the state House on Monday, with lawmakers weighing how to proceed after the U.S. Supreme Court struck down parts of Voting Rights Act protections for minority districts. The debate comes as Republicans seek a map that could produce a clean sweep of the state’s seven U.S. House seats, a target that has sharpened redistricting fights across multiple states in recent weeks.

The effort in South Carolina drew attention to how the Supreme Court ruling has been used by Republicans in other states. In the wake of the decision, disputes have played out in places including Tennessee, Alabama and Louisiana, where Republicans have argued they can redraw districts with large Black populations that have elected Democrats.

In South Carolina, the House discussion focused not only on the map itself but also on the political and procedural ripple effects of changing congressional boundaries mid-decade. Republicans said the redistricting effort is tied to broader national strategy as the midterm election season approaches, but some members raised concerns about whether the changes could dilute Republican voters enough to endanger districts currently held by Republicans.

One of those critics, State Rep. Nathan Ballentine, said he had asked constituents whether they support redistricting and reported that more than half of “reliable Republicans” who voted in at least four recent GOP primaries opposed it. Ballentine also said, “My mama raised me just because you can doesn’t mean you should,” framing his reservations in personal terms rather than as a purely procedural objection.

Supporters of redistricting have focused on the potential to reshape political outcomes in future U.S. House races, while Democrats pointed to complications that can arise when redistricting diverges from normal timelines and processes. Democratic state Rep. Annie McDaniel said an adopted amendment showed how congressional redistricting outside normal procedures creates additional problems, describing what she called “confusion on top of confusion on top of confusion.”

The House also moved to control the pace of deliberations. After Republicans voted nearly unanimously to limit debate, each House member would be allowed one amendment and three minutes to advocate for changes to the bill, even as there were over 600 amendments on the desk when the change was made. Democratic Rep. Spencer Wetmore said she did not know of another time the House has limited the number of amendments filed, and Democratic Rep. Wetmore said, “We’re changing the rules in the middle of the game.”

Beyond district lines, the debate addressed election timing and related rules. Some absentee and overseas military votes already had been cast for South Carolina’s June 9 primaries, and early in-person voting was scheduled to begin May 26. In addition to redrawing congressional districts, legislation pending in the House would move the U.S. House primaries to August if it cleared the House, with the next step requiring Senate action.

Republican Gov. Henry McMaster, who called lawmakers into a special session on redistricting, said it was important for South Carolina to send as many Republicans to Washington as possible to prevent Democrats from taking control of the House and attempting to impeach President Donald Trump. At the same time, some Republicans expressed concern that a 7-0 House map could spread Republican voters too thin, potentially making some Republican-held seats vulnerable to Democratic victories.

The debate unfolded as courts continued to weigh redistricting moves in other states following the Supreme Court’s Louisiana-related action. The House session highlighted that redistricting typically occurs at the start of each decade using census figures, but South Carolina’s process shows how lawmakers are grappling with mid-decade changes and their knock-on effects for political primaries and appointments tied to congressional districts.
