COLUMBIA, S.C. (AP) — A new map for South Carolina’s U.S. House seats is on its way to the governor after the state House approved the plan without any additional debate.

The plan makes minimal changes to the seven current districts, six of which reliably elect Republicans.

The House voted 72-33 on Wednesday to accept changes the Senate made last week. All the votes against the bill were from Democrats.

With Republicans holding a 6-1 advantage in U.S. House seats, there was little desire among their members to make significant changes beyond balancing out the 500,000 people South Carolina added in the past decade.

Both sides expect a lawsuit over the map.
