2026 State Elections Could Reshape Trifecta Control (States to Watch)

It's early, but never too early to talk about elections. This is a big year for gubernatorial elections, with governor seats in 36 states up for election, and at least half of those elections will be for open seats. But voters will also decide the fate of roughly 5,800 state legislative seats on Nov. 3, 2026. Because so many governors' races are competitive, legislative control matters even more — a party sweep in any of these states could produce a trifecta with real policy-making power. We still have nine long months before Election Day, and a lot can, and likely will, happen between now and then, but let's take an early look at the legislative chambers we can expect to be competitive this year.

The political forecasters at Sabato's Crystal Ball released their first look at the state legislative map last month. Their list of toss-up and "lean" legislative chambers was not much of a surprise. In fact, these are essentially the same states as our "states to watch" for legislative chambers in early 2024.

Most Competitive State Legislative Races in 2026 (Toss-Up Legislative Chambers)

Sabato's Crystal Ball rates 9 legislative chambers in 5 states as "toss-ups" at this point, which means there's a 50-59% chance that either party wins the election, according to the forecaster.

Arizona House (R) and Senate (R)

The Arizona legislature has been under narrow Republican control ‌for the last few election cycles, but Democrats have been unable to break the GOP majority. In fact, Republicans have maintained control of both chambers of the legislature for decades. Is this the Democrats' year? If they are able to pull it off in the 2026 midterms, the prize could be a Democratic trifecta (presuming a reelection for Gov. Hobbs, a gubernatorial race itself rated as a toss-up). But in an election favoring Republicans, the GOP could see their own trifecta return.

Michigan House (R) and Senate (D)

Democrats gained a trifecta in Michigan after the 2022 elections, but Republicans broke up the trifecta by winning back a majority in the House in 2024. This is another state with a toss-up governor's race, so a trifecta is in the cards for whichever party has a good night on Nov. 3.

Minnesota House (tied) and Senate (D)

Similar to Michigan, Republicans were able to break up the Democratic trifecta in Minnesota after the 2024 elections by gaining enough seats to tie the House, requiring a power-sharing agreement. An open governor's race in Minnesota is currently rated as a likely hold for the Democrats. This is another state where a good Democratic performance could easily put them back in control of a trifecta they recently lost.

Wisconsin House (R) and Senate (R)

This might be the most interesting state on the list. In 2023, the state supreme court ruled the GOP-drawn maps unconstitutional. The new maps put both the House and Senate in play for Democrats. Although Democrats came up short of a majority during the 2024 elections in the House, the Senate wasn't up during that election, so both chambers will be in play this November. The open governor's seat is a toss-up this year. Notably, Democrats haven't held majorities in either legislative chamber since losing control of the legislature in 2010. This is another state where a trifecta is on the table for either party.

New Hampshire House (R)

The 400-seat House in New Hampshire is perennially on this list because with so many members in such a small state, it's hard to predict which way the political winds will blow. Right now, Republicans hold a 217 to 177 majority in the chamber.

States Where One Party Holds Slight Advantage ("Lean" Chambers)

For chambers Sabato's Crystal Ball rates as "leans" for one party or the other, this translates to that party having a "small edge" equating to a 65-80% chance of winning.

Pennsylvania House (D) and Senate (R)

The Keystone state's legislature has been split between a Democratic majority House and a Republican majority Senate since 2023. The early forecast gives a slight "lean" rating for each party to keep majorities in their respective chambers. But if Democrats can flip the three seats necessary to take a majority in the Senate this November, they'd likely be looking at a trifecta in Pennsylvania for the first time since 1993.

New Hampshire Senate (R)

Forecasters expect Republicans to hold majorities in the Senate, a much smaller chamber than the House, rating it as "Lean Republican." The current GOP majority is a solid 16-8. But with a governor's election too, this is another opportunity for Democrats to flip a Republican trifecta into a Democratic trifecta if they have a big election night. But those odds are not as strong as some of the states above.

Maine House (D)

Finally, Democrats hold a trifecta in Maine, but forecasters have noted that their numbers in the House, 74-72 seats, are narrow and thus vulnerable for Republicans to capture a majority and break up the trifecta.

What Makes 2026 Elections Particularly Consequential

Every year is an election year for the states, but 2026 stands out as the most consequential cycle since 2022. With trifectas on the line in at least five states and new maps reshaping competition in places like Wisconsin, the stakes extend well beyond individual chamber control. Primary season and candidate recruitment over the next few months will clarify whether these early ratings hold or whether the map shifts further toward one party.
