Democrats' Prospects Dim as GOP-Led States Redraw Congressional Maps Ahead of 2026 Midterms
Democrats' chances of regaining control of the House of Representatives have decreased as several Republican-led states in the South have redrawn their congressional maps. This redistricting effort follows the U.S. Supreme Court's decision in Callais v. Louisiana, which struck down a second majority-Black district in Louisiana. The ruling has emboldened other conservative states to adjust their maps, potentially allowing Republicans to gain seats. Prediction markets like Kalshi and Polymarket have shown a decline in Democrats' chances of flipping the House, with Kalshi reporting a drop from 86% to 74% and Polymarket from 87% to 80% over the past month. Despite these setbacks, Democrats still hold a lead in generic ballot polls, but the redistricting changes mean they will need a larger margin to secure a majority.
