A court-ordered redistricting do-over in Georgia put one U.S. House seat in play — a potential pickup for Democrats — but the state is far from alone.

Lawsuits over representation and discrimination are playing out across several states, many of them in the South, with the potential to tip the balance of power in Congress after next year’s elections….

“A single seat could turn out to be quite important come 2024,” said Doug Spencer, a University of Colorado election law professor who manages the All About Redistricting website. “Georgia has become the center of the political universe.”

Spencer estimated that nationwide, pending redistricting cases could swing partisan control by four to six seats in the House.

“There are a cluster of mostly Southern states that have essentially white, Republican-dominated legislatures that have drawn districts that help Republicans,” said Rick Hasen, an election law professor at the University of California, Los Angeles. “It’s so high-stakes because control of the U.S. House of Representatives could be at issue.”
