PHOENIX (AP) — Democrats in Arizona won control of both legislative chambers and retained the governor's office, giving the party its first trifecta in the state since 1966 as Democrats made major gains nationwide in this week's elections and took control of both chambers of Congress.

In her first term, Democratic Gov. Katie Hobbs had vetoed more than 540 measures passed by the Republican-led Legislature on policies including taxes, immigration and voting laws. Hobbs has said she's looking to address water issues and affordability, and take on fraud and abuse in the state's school voucher program.

The Associated Press called enough legislative races to confirm that both chambers flipped on Friday. The news organization calls races individually and it can take several days after voting, depending on when election officials tally the votes and how close the elections are. There have not been major disputes or disruptions this year.

In Arizona, Republicans have held the House for 60 years and the Senate since the early 1990s.

Overall, Democrats took full control — both statehouse chambers and governors’ offices — in at least six states where they previously shared power with Republicans. Besides Arizona, those wins were in the battleground states of Michigan, Minnesota, Pennsylvania, Nevada and Wisconsin.

The flips weren't just in states that are normally competitive. Democrats won control of the Texas House, which Republicans have held since 2003, and elected Gina Hinojosa as the state's first Democratic governor since George W. Bush ousted Ann Richards in 1994. Republicans held onto the state Senate.

Democrats also flipped the lower chambers of the legislatures in Maine and North Carolina and both chambers in New Hampshire, where Republican Kelly Ayotte was reelected. The count could grow as results are tallied in additional states.

The National Council of State Legislatures says it's likely to end up as the election with the most legislative seats and chambers changing parties since the 2010 election, when Republicans took over governments across the country amid the Great Recession.

Democrats will also hold the governor's office in at least 28 states. Results are still pending in Alaska and Kansas.
