The struggle for control of the Arizona Legislature is playing out across a series of districts where Republican incumbents, prominent political figures and longtime GOP strongholds face unexpectedly strong Democratic challenges.

Although Democrats held leads in enough races Wednesday morning to take control of both legislative chambers, individual contests remained unresolved. Some districts showed the possibility of complete Democratic sweeps, while others produced surprisingly close results or split-ticket outcomes.

Here is a closer look at the districts driving Arizona’s legislative shakeup.

LD2: Bolick Trails as Voters Split Their House Choices

Republican Sen. Shawnna Bolick, who narrowly won reelection in 2024, faced a difficult political landscape Wednesday morning.

Democrat Amelia Gallitano led Bolick with 31,195 votes to 22,294 in early unofficial returns, an advantage of 8,901 votes.

The north Phoenix district has been closely contested in recent elections. Bolick defeated Democrat Judy Schwiebert by fewer than 4,000 votes in 2024, when the district elected one Republican and one Democrat to the House.

That divided House delegation appeared likely to continue. Democratic incumbent Stephanie Simacek led the three-candidate House contest, while Republican incumbent Justin Wilmeth held second place ahead of fellow Republican Paul Carver.

If the results hold, LD2 would replace its Republican senator while maintaining bipartisan House representation.

LD4: An Expensive Republican Defense Comes Apart

Legislative District 4, covering portions of Scottsdale and Phoenix, was among the election’s most heavily contested legislative battlegrounds.

The Senate race between Republican incumbent Carine Werner and former Democratic state Rep. Aaron Lieberman attracted more spending than any other legislative contest leading into the general election, according to the Arizona Capitol Times.

In Wednesday’s early Maricopa County returns, Lieberman led Werner by 6,307 votes, 55,256 to 48,949.

The House results looked even more troubling for Republicans.

Democrats Tammy Caputi and Karen Gresham held the top two positions ahead of Republican incumbents Matt Gress and Pamela Carter. All three legislative seats in LD4 were held by Republicans entering the election.

Gress, who has cultivated a reputation as an influential voice on education and budget matters, faced the possibility of losing his seat despite his legislative prominence.

If all three Democratic leads survive, LD4 would deliver one of the election’s most significant partisan reversals.

LD9: Democrats Defend Their West Mesa Stronghold

Not every competitive legislative district represented a potential Democratic pickup.

In west Mesa’s LD9, Democratic Sen. Kiana Sears held a substantial early lead over Republican Bridget Fitzgibbons, while Democratic incumbent Lorena Austin and fellow Democrat Jacob Martinez led Republican Bradley Bettencourt for the district’s two House seats.

Despite the district’s competitive reputation, Republicans have not won a legislative seat there since the current district boundaries were established following the 2021 redistricting.

The results suggest that Democrats were successfully defending their existing foothold in Mesa even as they challenged Republican incumbents elsewhere in the Valley.

LD13: Chandler Republicans Face a Complete Shutout

In Chandler-area Legislative District 13, Republicans faced the possible loss of all three legislative seats.

Democrat Kristie O’Brien led Republican state Rep. Julie Willoughby by 7,841 votes in the Senate race, according to early Wednesday Maricopa County returns.

Willoughby was seeking to move from the House to the Senate, but the results suggested that her existing legislative experience was not translating into an advantage with district voters.

The House contest featured two other prominent Republican candidates: Chandler Mayor Kevin Hartke and Janet Weninger, wife of Republican state Rep. Jeff Weninger.

Both trailed Democrats Rockee Armstrong and Jacob Weinberg.

The results were especially striking because Republicans had recruited recognizable local political figures for the district’s legislative races. Neither Hartke’s position as mayor nor the Weninger family’s established political connections appeared sufficient to prevent Democratic leads across the ticket.

LD13 could become another three-seat Democratic pickup if those leads hold.

LD14: A Biggs Family Defeat and a Republican House Divided

Gilbert-area Legislative District 14 delivered one of the election’s most politically intriguing results.

Democrat Stephanie Walsh led Republican Mylie Biggs, daughter of Republican gubernatorial candidate Andy Biggs, by 2,416 votes in the Senate contest.

The district has elected only Republican state legislators since the current boundaries took shape. A Walsh victory would therefore represent a significant break with its recent electoral history.

The House race produced a different kind of surprise.

Democrat Mary Rose led the field, while Republicans Tyler Farnsworth and incumbent Laurin Hendrix competed closely for the second seat.

Because Arizona’s House districts elect two representatives, Rose’s lead did not necessarily mean both Republican candidates would lose. Instead, Republicans were fighting to retain one of the district’s two House seats.

The result could leave LD14 represented by a Democratic senator and a divided House delegation, a remarkable outcome for a district that had been reliably Republican.

LD16: Shope’s Political Future Hangs on a Narrow Margin

One of the tightest consequential Senate races was unfolding in Legislative District 16, which includes portions of Pinal, Pima and Maricopa counties.

Democrat Elaine Aldrete led incumbent Republican Sen. T.J. Shope by just 1,238 votes, 33,102 to 31,864, in Wednesday’s unofficial statewide reporting.

Shope, a prominent legislative leader from Coolidge, had been discussed as a potential Senate president if Republicans retained control of the chamber.

His defeat would represent more than the loss of a single Republican seat. It would remove a veteran legislator from the Capitol and eliminate one of the party’s potential leadership figures.

The district’s House contest also threatened a Republican seat.

Democrat Julia Romero Gusse led the three-candidate race, with Republican incumbents Teresa Martinez and Chris Lopez competing for the remaining position. Lopez occupied third place in the returns reviewed Wednesday.

Republicans captured both House seats in 2024. A Gusse victory would break that two-seat hold.

Unlike some districts with large Democratic leads, LD16 remained close enough in its Senate race to warrant particular attention as additional ballots are counted.

LD17: Tucson Democrats Build on Their 2024 Breakthrough

Tucson-area Legislative District 17, long considered a competitive district, appeared to be shifting further toward Democrats.

Democrat Edgar Soto led Republican Christopher King in the race to succeed retiring Republican Sen. Vince Leach. Wednesday’s unofficial statewide returns placed Soto ahead by 58,006 votes to 48,359.

The district had already shown signs of political change in 2024, when Democrat Kevin Volk won a House seat while Leach narrowly retained the Senate seat.

This year, Volk sought reelection alongside fellow Democrat Holly Lyon. Both Democrats led Republican John Winchester and incumbent Republican Rep. Rachel Keshel in the four-candidate House race.

If those results stand, Democrats would control all three legislative seats in LD17, turning a district that was closely divided two years ago into a significant Democratic stronghold in the Tucson area.

LD23: Peña’s Unusual Winning Streak Faces a Test

Legislative District 23 offered a different kind of political contest.

Republican Rep. Michele Peña, who won elections in 2022 and 2024 despite representing a heavily Democratic district, faced the possibility that her unusual electoral success had finally reached its limit.

Democratic incumbent Mariana Sandoval and fellow Democrat Emilia Cortez held the top two positions in the House race, each attracting roughly 32% of the votes cast for candidates in the contest.

Peña trailed with approximately 19%, while Republican Gary Garcia Snyder was further behind.

Peña had previously won in the Democratic-leaning district without another Republican competing alongside her. This year, both parties fielded two candidates.

A Democratic sweep would eliminate one of the more unusual Republican electoral successes in Arizona legislative politics and restore both House seats to Democrats.

LD25: A Republican Stronghold Produces a House Scare

Legislative District 25, which includes parts of the West Valley and southwestern Arizona, was another district where Republicans faced an unexpected challenge.

Republican Sen. Tim Dunn led Democrat Laura Huber, but the House contest was substantially closer.

Republican incumbent Michael Carbone led the field, while fellow Republican incumbent Nick Kupper and Democrat Tiffany Byrne remained locked in a close struggle for the second House seat.

Earlier returns briefly placed Byrne ahead of Kupper, illustrating how narrow the contest had become.

The race offered Democrats an opportunity to win a House seat in territory that normally favors Republican candidates by comfortable margins.

Unlike districts where Democrats fielded two House candidates, Byrne needed only to finish ahead of one Republican to secure a seat.

LD27: Democrats Break Into Republican Territory in Peoria

Few districts illustrated the breadth of the Democratic challenge more clearly than Legislative District 27, which includes portions of Peoria and the northwest Valley.

Democrat Kyle Clayton led Republican Sen. Kevin Payne by 3,721 votes in Wednesday’s early Maricopa County returns.

The district hadn’t elected a Democrat to the Legislature since the current boundaries establsihed.

In the House race, Democrat Deborah Howard led both Republican incumbents, Lisa Fink and Tony Rivero.

Because Howard was the only Democrat seeking a House seat, Republicans were guaranteed the second position if the three-candidate field remained unchanged. But the prospect of Democrats winning both the Senate seat and one House seat represented a substantial reversal in a district long controlled by Republicans.

The LD27 results could be among the clearest indications that the Democrats’ strong election-night performance extended beyond the Valley’s traditional swing districts.

LD29: A Democratic Surprise Threatens the House Speaker

Legislative District 29, covering portions of the West Valley, produced one of the election’s more complicated results.

Republican Sen. Janae Shamp trailed Democrat Eric Stafford in initial election-night reporting but moved ahead as additional returns came in.

By early Wednesday morning, Shamp led Stafford by 2,270 votes in Maricopa County returns.

The House race nevertheless offered Democrats a significant opportunity.

Democrat Christine Scianna led the three-candidate field, while Republican House Speaker Steve Montenegro narrowly held the second position ahead of fellow Republican Rep. James Taylor.

If those positions hold, Montenegro would survive reelection but lose his Republican House colleague, while Scianna would claim the district’s other seat.

That outcome would be especially notable because the district has traditionally favored Republicans. It would also underscore how the broader political shift could affect the House speaker’s own legislative delegation.

The Seats Still in Play

The district results offer a more complicated picture than a simple statewide partisan wave.

In Scottsdale and Chandler, Democrats threatened complete sweeps of Republican-held delegations. In Gilbert, Peoria and the West Valley, they were breaking into districts that had recently elected only Republicans. In Tucson, Democrats appeared ready to build on legislative gains made in 2024.

Other districts, including LD16, LD25 and LD29, remained competitive enough that the final results could change as counties complete their counts.

All results are unofficial. Arizona’s statewide canvass is scheduled for November 23.
