Republicans Could Gain Significant Structural Advantage in House if Voting Rights Act Section Struck Down

The potential striking down of part of the Voting Rights Act in Louisiana v. Callais by the Supreme Court could result in Republicans gaining control of the House of Representatives, even if they lose the popular vote, due to the elimination of up to a dozen Democratic-held districts in the South. Republicans have been redrawing congressional districts this year at President Trump's behest, but so far, it has been insufficient to deny Democrats a reasonable path to control the House. The court's decision is likely to come after many state primaries, and the full fallout might not be realized until 2028 or the next census in 2030.

Key Takeaways:

• Republicans may eliminate up to a dozen Democratic-held majority-minority districts across the South if Section 2 of the Voting Rights Act is struck down.
• This could result in a significant structural advantage for Republicans, allowing them to win the House even if they lose the popular vote by a wide margin.
• Republicans may not eliminate every Democratic-leaning district they could technically eliminate, but the party's aggressive mid-cycle redistricting suggests they would remove enough districts to gain a structural advantage.
• In the absence of Section 2, state legislatures would be free to eliminate majority-minority congressional districts, mostly voting Democratic.
• The estimated number of districts Republicans would eliminate is uncertain, ranging from a half-dozen to over a dozen districts.
• Removing every Democratic-held majority-minority district in states like Alabama, Mississippi, South Carolina, Louisiana, and Tennessee would not be surprising, and other states like North Carolina and Florida may also see significant changes.
• Republicans would face limitations in eliminating additional Democratic seats, including concerns about endangering Republican incumbents and potential opposition from Republican members of Congress or state legislators.

Statistics:

• Up to a dozen Democratic-held districts could be eliminated across the South if Section 2 is struck down.
• An estimated 5-to-10-point margin in the popular vote might be insufficient for Democrats to win the House, assuming the Republicans eliminate up to a dozen districts.
• The number of districts Republicans can eliminate safely is constrained by concerns about protecting Republican incumbents and potential opposition within the party.
• The estimated number of districts Republicans can safely eliminate is between 7 to 8 districts.
• A maximum gerrymander in Texas might require a near-total reconfiguration of the state's congressional map, with districts covering long distances and potentially crossing state borders.
• In the 1994, 2006, 2010, and 2018 elections, large majorities won the popular vote when one party gained the majority.
