Cook Political Report: Democrats Hold Narrow House Edge as 2026 Midterms Open

The Cook Political Report's August 25 ratings give Democrats a structural edge in the House battleground: 21 Democratic-leaning competitive seats versus 27 Republican-leaning ones. The swing-district universe of roughly 48 seats is small enough that a late-cycle shift could quickly redraw the map. The ratings count 184 Solid Democratic seats and 182 Solid Republican.
