Democrats won control of the Arizona House and Senate and retained the governor’s office on Friday, Nov. 6, 2026, securing the party’s first trifecta in the state since 1966. Gov. Katie Hobbs defeated Republican Andy Biggs, and the Associated Press projected Democrats hold majorities in both chambers, according to AP projections.

The Associated Press projected Democrats will hold 17 seats in the Arizona Senate and 31 seats in the House, according to FOX 10 Phoenix. KTAR reports Democrats are on track to finish with a 20-10 Senate majority and a 37-23 House advantage. The sources disagree on exact seat counts.

Republicans had held the Arizona House for 60 years and the Senate since the early 1990s, according to HuffPost and FOX 10 Phoenix.

Arizona Democrats last held majorities in the Senate in 1992 and the House in 1966, KTAR reported.

Hobbs, in her first term, defeated Republican Andy Biggs. Hobbs previously vetoed more than 540 measures passed by the Republican-led Legislature on policies including taxes, immigration and voting laws, according to HuffPost.

Hobbs said she is looking to address water issues and affordability, and take on fraud and abuse in the state’s school voucher program, HuffPost reported. Senate Minority Leader Priya Sundareshan, in line to become Senate president, said her party is ready to act on rising costs, protecting the state’s water supply, investing in education and putting guardrails on the Empowerment Scholarship Account school voucher program, according to KTAR.

“We have been ready to go at the beginning of this year with a set of legislation addressing those issues,” Sundareshan said, according to KTAR. “Unfortunately, it was held up in the extreme governance that the Republicans held over the Legislature. But these are things that we know the vast majority of Arizonans want to see, and we’re excited to deliver on that.”

Republicans worked with a 33-27 majority in the House and a 17-13 advantage in the Senate the past two years, KTAR reported. Republicans clung to one-seat majorities in the House after the 2018, 2020 and 2022 elections and won by a single seat in the Senate in 2020 and 2022. The GOP teetered on the brink of losing control several times in recent elections as independents became the state’s largest voting bloc, according to KTAR.

Democrats took full control of both statehouse chambers and governors’ offices in at least six states where they previously shared power with Republicans, including Arizona, Michigan, Minnesota, Pennsylvania, Nevada and Wisconsin, according to HuffPost and FOX 10 Phoenix. Democrats also won control of the Texas House, which Republicans had held since 2003, and elected Gina Hinojosa as the state’s first Democratic governor since George W. Bush defeated Ann Richards in 1994. Republicans held onto the Texas state Senate.

Democrats flipped the lower chambers of the legislatures in Maine and North Carolina and both chambers in New Hampshire, where Republican Kelly Ayotte was reelected, according to HuffPost. Democrats will hold the governor’s office in at least 28 states, with results still pending in Alaska and Kansas.

The Associated Press calls races individually, and it can take several days after voting, depending on when election officials tally votes and how close elections are. There have not been major disputes or disruptions this year, according to HuffPost.

The National Council of State Legislatures said it is likely to end up as the election with the most legislative seats and chambers changing parties since the 2010 election, HuffPost reported. Nationally, Democrats claimed majorities in the U.S. House and Senate, according to KTAR. In Arizona, Democrats also swept the statewide offices and picked up two congressional seats.
