2026 Battleground Tracker
Every competitive Senate and House race rated, ranked, and tracked. Generic ballot D+6 puts Democrats on track for a House majority if the environment holds. Four Senate seats in genuine toss-up territory — any two flips could shift the balance of power.

Key House Battlegrounds
Republicans hold a 5-seat majority. Democrats need just 5 net seats to flip control. With D+6 generic ballot, historical models project 25-35 Democratic pickups. Below are the most competitive Republican-held seats.
| District | Incumbent (R) | 2024 Pres. Margin | 2022 Margin | Rating |
|---|---|---|---|---|
| NY-22 | Brandon Williams | D+4 | R+0.4 | Toss-up |
| NY-17 | Mike Lawler | D+6 | R+0.6 | Toss-up |
| AZ-6 | Juan Ciscomani | R+1 | R+0.7 | Toss-up |
| CA-27 | Mike Garcia | D+3 | R+0.8 | Toss-up |
| PA-7 | Open (R) | R+2 | R+2.1 | Lean R |
| NJ-7 | Tom Kean Jr. | R+3 | R+0.8 | Lean R |
| CO-8 | Gabe Evans | R+0.5 | R+0.5 | Toss-up |
| ME-2 | Jared Golden (D) | R+12 | D+0.4 | Lean D |

The Path to a Democratic Majority
Minimum Path: Net +5
Democrats need only 5 net seats — the slimmest margin in modern history. If NY-22, NY-19, AZ-6, CA-27, and CO-8 all flip (all currently toss-ups), Democrats win the majority even if they lose every other race. This minimum path is achievable even in a neutral political environment.
Base Case: Net +20-30
With D+6 generic ballot sustained through November, historical models project 25-35 Democratic gains. This would produce a House majority of 235-245 Democratic seats — large enough to be stable and able to pass legislation without losing many moderates.
Wave Scenario: Net +35-45
If conditions worsen for Republicans (Trump approval drops to 39-40%, economic recession materializes), a 2018-style wave is possible. In 2018, D+8.6 generic ballot produced D+41 seats. A similar wave would flip every Lean R and Toss-up district and threaten some Likely R seats.
