A trifecta is unified control of the governor's office and both legislative chambers. Every two years we ask the same question ahead of November: if one party won every competitive race on the ballot, what would the map of state governments look like? The two hypothetical maps below are the outer bounds of 2026, not predictions. The real result will land somewhere in between.
What Counts as a Sweep
A sweep means one party wins every governor race and every legislative chamber that forecasters rate as competitive: Toss-up, Tilt, or Lean. Races rated Likely, Very Likely, or Solid stay with the favored party. Governor races use MultiState's consensus rating, the average of the Cook Political Report, Sabato's Crystal Ball, and Pluribus News. Legislative chambers use Sabato's Crystal Ball ratings.

The Races That Decide It
| State | Today | Governor | House | Senate | Dem Sweep | GOP Sweep |
|---|
Races rated Toss-up, Tilt, or Lean flip under a sweep; Likely, Very Likely, and Solid races stay with the favored party. Party in parentheses is the current officeholder's. "Not up" chambers are not on the 2026 ballot.
Methodology and Sources
- Governor ratings are MultiState's consensus: the average of the Cook Political Report, Sabato's Crystal Ball, and Pluribus News, as shown on the 2026 governors page.
- Chamber ratings are from Sabato's Crystal Ball's 2026 state legislative outlook (February 2026), as shown on the 2026 legislatures page.
- Alaska's House and Senate are run by bipartisan coalitions with Republican numeric majorities, and both are rated Likely Coalition. The coalitions are treated as holding under either sweep, so Alaska stays divided in both scenarios no matter who wins the open governor race.
- Minnesota's House is tied 67–67 under a power-sharing agreement and rated Toss-up, so it goes to the sweeping party in both scenarios.
- Nebraska's unicameral legislature is officially nonpartisan and is counted as Republican-controlled.
- Chambers not on the ballot in 2026 keep their current control. Governors not up in 2026 keep their seats.
- This is the 2026 edition of an analysis MultiState first published in September 2024. Ratings change; the page regenerates from the current forecasts with every data update.
