Toss-ups, triage and targets: How to read the wide-open 2026 House map

Roughly a month before Election Day, the spending choices of both parties suggest the live question is the size of a Democratic House majority rather than whether Democrats win one. Republicans now hold the chamber 218-214. Cook Political Report counts 43 competitive districts, 22 of them toss-ups, up from 39 and 18 when it first rated the races in February 2025. Yet NPR's review of party target lists, advertising reservations and Trump-aligned super PAC outlays shows money flowing into more than 90 districts.

Several forces are reshaping the contest. Voters are unhappy about the war in Iran, gas prices, tariffs and immigration enforcement, and strong disapproval of President Trump is higher than at any earlier point in his presidencies. Anti-incumbent anger has produced record retirements and primary losses. Mid-decade redistricting also changed lines for about one in ten registered voters, though some maps may backfire. In North Carolina's 1st District, Representative Don Davis holds a seat redrawn to lean more conservative, but over $20 million in ad reservations has made it among the costliest House contests.

Sixty districts appear on the priority lists of both national party committees and allied super PACs; Trump carried them by 8% on average.
