Another special-election result this week reinforced a pattern that could make 2026 a Democratic year. Republicans held a Tennessee seat, but their margin fell from a 22-point win in 2024 to just nine points in the special — one more example of Democrats overperforming recent benchmarks by wide margins.
Across several 2025 contests, Democrats have on average improved roughly 14 points versus 2024 baselines (using 2024 presidential results as the comparison and including the New Jersey and Virginia governor races). The individual changes were:
– FL-1: 2024 R+32 → 2025 R+15 (Democratic gain of 17 points)
– FL-6: 2024 R+33 → 2025 R+14 (Democratic gain of 19 points)
– VA-11: 2024 D+34 → 2025 D+50 (Democratic gain of 16 points)
– AZ-7: 2024 D+27 → 2025 D+39 (Democratic gain of 12 points)
– VA Governor: 2024 D+6 → 2025 D+16 (Democratic gain of 10 points)
– NJ Governor: 2024 D+6 → 2025 D+14 (Democratic gain of 8 points)
– TN-7: 2024 R+22 → 2025 R+9 (Democratic gain of 13 points)
Redistricting and the courts
The Supreme Court this week cleared a new Texas congressional map to stand, in a 6-3 decision that rejected a lower-court finding of illegal racial gerrymandering. The conservative majority signaled the map may be a permissible partisan gerrymander, and Republicans project it could yield about five additional seats in Texas. That matters because the GOP’s House majority is extremely narrow — roughly three seats — so a handful of pickups or losses could flip control.
But redistricting is not an unalloyed advantage for Republicans. Democrats are preparing new maps in California and possibly Virginia, and a judge recently approved a Utah map likely to add a Democratic-leaning seat. Moreover, converting safe Republican districts into more marginal Republican-leaning seats can backfire if 2026 turns into a Democratic wave.
Voting blocs and the political environment
Regions like South Texas will be important to watch. Republicans had expected Latino turnout to remain favorable to Trump, but multiple polls show Latino attitudes cooling because of the economy and immigration policies. Recent surveys offered contrasting snapshots: an NPR/PBS News/Marist poll found a majority of Latinos disapproved of Trump’s job performance, while a larger Pew Research Center study showed 70 percent disapproval and a notable drop in support among those who had voted for Trump.
Economic perceptions are the central vulnerability for Republicans. Nationwide polling shows many Americans think the economy is getting worse. Gallup reported economic confidence at a 17-month low with only 27 percent saying the economy is improving and 68 percent saying it is getting worse. Other polls underscore the pocketbook strain: large shares of voters report paying higher prices because of tariffs and rising grocery costs, and relatively few favor raising tariffs.
Trump’s rhetoric has not reversed those trends. Some surveys find even substantial shares of Trump voters say the cost of living is the worst they can remember and that the president is not doing enough. Republican candidates in some recent contests have tried to focus on concrete cost-of-living issues rather than echoing dismissive language, but Democratic gains have happened even in high-turnout races.
What it means for 2026
The combination of Democratic overperformance in 2025 contests, unfavorable economic perceptions, and ongoing demographic shifts suggests Republicans’ path to holding the House depends on either improving economic sentiment or benefiting from structural advantages like redistricting. If neither of those things materializes, and if 2026 resembles the recent special and gubernatorial results, control of the House could be in play for Democrats. A related indicator to watch is the number of House Republicans choosing to retire rather than run again, which already hints at unease about the electoral landscape.
