PHOENIX — Sixty years of Republican control of the Arizona Legislature appeared to end on election night. At the Arizona Democratic Party's celebration in a downtown Phoenix hotel ballroom on Tuesday night, the party's two legislative leaders claimed both chambers outright. “We are thrilled to announce that there will be a Democratic majority,” said Oscar De Los Santos, the Democratic leader in the state House, according to Governing magazine's report of the event, which first appeared in the Arizona Mirror. De Los Santos and his Senate counterpart, Priya Sundareshan, were introduced to the crowd as the next House speaker and Senate president. Combined with Governor Katie Hobbs's reelection, the results would give Democrats a “trifecta” — the governorship and both legislative chambers — for the first time since the 1960s.

The caution belongs in the same paragraph as the celebration: hundreds of thousands of ballots had yet to be counted when the claims were made, control of neither chamber had been independently confirmed race by race, and Arizona's slow count — driven by early ballots dropped off on Election Day, especially in Maricopa County — means final numbers will move for days. The Arizona Globe reported that Democratic candidates were leading in more than a dozen legislative contests, some in districts not generally regarded as battlegrounds, while noting that “early advantages are not the same as confirmed victories.” What is not in dispute is the direction and scale of the leads.

What the early counts show

As of 10 p.m. on election night, Democrats held large leads in seven Senate seats and nine House seats currently held by Republicans, many of them in Maricopa County, which had not yet tallied Election Day votes or early ballots dropped off at polling places, Governing reported. If those counts hold, Democrats go from a solid minority — 13 of 30 Senate seats and 27 of 60 House seats — to commanding majorities of 20 Senate seats and 36 in the House. Republicans entered Election Day holding the House 33–27 and the Senate 17–13, the Arizona Globe reported; Democrats needed net gains of four House seats and three Senate seats to take both chambers, and the early returns pointed well past both marks. By 5 a.m. Wednesday, the Tucson Spotlight reported Democrats leading in 20 of 30 state Senate districts and for 37 of 60 House seats, alongside Hobbs's statewide lead of 1,193,939 votes (55.6 percent) to Republican Andy Biggs's 916,236 (42.7 percent).

Sundareshan marked the claim with a piece of Arizona symbolism: she showed the crowd her bolo tie — the state's official neckwear — set with three blue gemstones, calling it her “trifecta bolo” for the two chambers plus the Governor's Office. The Democratic Legislative Campaign Committee, the party's national state-legislative campaign arm, declared the flips in a statement on Wednesday, calling them “one of the largest political earthquakes in modern history” and the first Democratic trifecta in Arizona since the 1960s. That is a partisan source celebrating its own wins, and this report treats it as such — but it matches what the neutral counts showed on the night. The Associated Press also projected new terms for the state's Democratic attorney general, Kris Mayes, and secretary of state, Adrian Fontes; Votebeat noted that a trifecta, the first since 1966, could give Fontes added leverage to push changes to Arizona's voting laws and procedures.

Why 1966? The one-person, one-vote earthquake

The 60-year gap has a precise origin. Before 1966, Democrats controlled Arizona government through a representation system that apportioned seats in the state House and Senate by county; because there were more rural counties, and they were populated largely by Democrats, urban and Republican lawmakers were left in the minority, Governing explained. In 1964, the US Supreme Court's one-person, one-vote rulings held that such schemes treated voters unequally. Arizona was carved into 30 legislative districts of equal population, power shifted to urban voters in Maricopa and Pima counties — and Republicans have held at least one chamber of the Legislature ever since, until, apparently, this week.

What changes if the leads hold

For Hobbs, a friendly Legislature ends a first term defined by combat. Governing reported that she spent the term “warring” with a Republican House and Senate that sought to block her at every turn: the Senate turned confirmations of her agency nominees into politically charged hearings that left many state agencies without permanent leaders, and Hobbs set a state record for vetoes of bills sent to her by Republican lawmakers. A Democratic Senate can confirm her directors; a Democratic House and Senate can pass budgets and bills she will sign rather than veto. The same machinery runs in reverse for Republicans, who lose the power to set committee agendas, block appointments and pass bills over her veto — their remaining levers are the size of the Democratic majorities and the 2028 election.

Why it matters beyond the Capitol

Arizona is one of the country's fastest-growing states and a permanent presidential battleground, and state government — not Washington — decides much of daily life: school funding, water policy in a desert state, election rules, and the state highways, including the I-10 and I-17 freight corridors that Punjabi-American truckers drive daily between California, Phoenix and Texas. A trifecta also removes the checks that split government imposed: the same party will write the budget, run the committees and sign or veto the bills, which makes the new majority fully accountable for what does — and does not — change. The party's leaders have promised a governing agenda after 60 years out of power; the counts finishing this week will tell them exactly how much room they have to deliver it.

What happens next

Counting continues across Arizona's 15 counties, with updated unofficial results expected over the coming days and formal canvassing and certification to follow before the new Legislature organises in January, when De Los Santos and Sundareshan would formally take the speaker's and Senate president's gavels if the results hold. Hobbs begins a second term with, for the first time in her tenure, a Legislature of her own party. The Republican response will shape the next fight: with no chamber and no governorship, the state party's path back runs through the 2028 cycle and through any seats the late count returns to its column this week.
