Prop. 133: Protects partisan primary elections
The measure would enshrine partisan primaries in the Arizona Constitution.
- GOP lawmakers referred it to the ballot, where it will directly compete with a proposal to create nonpartisan open primaries in Arizona (Prop. 140).
Prop. 134: County-based signature requirements for citizen initiatives
The Republican-backed measure would amend the Arizona Constitution to require statewide initiative and referendum campaigns to collect a minimum number of signatures from each of the state's 30 legislative districts.
- Currently, campaigns can collect signatures from voters anywhere in the state, with percentage-based requirements ranging from 5-15% depending on whether it's a constitutional change, statutory change or citizen referendum.
Go deeper:
Prop. 135: Emergency powers
Republican state lawmakers pushed this ballot measure, which would limit the governor's power during an emergency. It was born out of GOP frustration over business closures during the COVID pandemic.
- Currently, the governor can declare a state of emergency during fires, floods, epidemics, riots and a handful of other major events. During the emergency, the governor has full control over state agencies and police operations until the governor or Legislature declares them over.
- This proposition would make it so that most emergencies automatically expire after 30 days and would require a majority vote of the Legislature to extend them.
Prop. 136: Easier to challenge citizen initiatives
The measure would allow people to challenge the constitutionality of citizen initiatives in court before they're actually passed.
Prop. 137: Eliminates most judicial retention elections
Under the current system, Arizona Supreme Court justices and Court of Appeals judges must go before the voters every six years for an up-or-down vote on whether they remain on the bench, and superior court judges in the most populous counties must do so every four years.
- The measure would change that system so judges only face retention elections if they're convicted of felonies or crimes involving fraud or dishonesty, if they file bankruptcy, have a mortgage foreclosed on, or if the Arizona Commission on Judicial Performance Review finds they don't meet performance standards.
- If it passes, any judges who lose retention elections this year would get to keep their seats, which is noteworthy given that Democrats are targeting Supreme Court Justices Clint Bolick and Kathryn Hackett King over their votes for a ruling to reinstate Arizona's pre-Roe abortion ban.
Go deeper:
Prop. 139: Arizona Abortion Access Act
The Arizona Abortion Access Act would permit abortions up to the point of fetal viability, around 24 weeks of pregnancy, which was the standard under Roe v. Wade.
- Abortions would be permitted past that point to "protect the life or physical or mental health" of the mother.
- The measure would also prohibit any law penalizing a person who helps someone get an abortion.
- Abortion is currently permitted in Arizona up to 15 weeks of pregnancy.

- Arizona will call fetuses "unborn human beings" in abortion initiative description
- How a $16 million Arizona abortion ad campaign could help Democrats
- Advocates say criticism of abortion ballot measure is misleading
- When Arizona women sought abortion care, by week
- The last time abortion was on the ballot, Arizona voters protected it
Prop. 140: Make Elections Fair Act
/2024/10/04/1728081895416.gif)
The proposal would replace Arizona's partisan primary system with a nonpartisan "open primary" in which all candidates appear on the same ballot, with the top vote-getters advancing to the general election, regardless of party affiliation.
- Arizona would have the option of having between two and five candidates go to the general election for each seat or office. If more than two candidates advance, the state would have to use a form of ranked-choice voting.
- Under ranked-choice voting, voters list candidates by preference, and if no candidate gets a majority, the candidate with the fewest votes is eliminated and their second-choice votes are given to the remaining candidates until someone has over 50%.
- The Legislature would be tasked with determining the details of Arizona's open primary system, but if lawmakers are unable to agree, the decision would go to the secretary of state.
Go deeper:
- Arizona Supreme Court says voters will decide on open primaries measure to overhaul elections
- Proposal would overhaul Arizona elections with nonpartisan open primaries
- Open primaries proposal won't require ranked choice voting, but opens the door
- Party activists' role in legislative appointments could end under open primaries initiative
Prop. 312: Property tax refund for nuisance issues
Prop. 312 would allow property owners to request a tax refund if their city or town does not enforce "nuisance" laws related to homelessness, like illegal camping, loitering and public urination.
- Proponents like the conservative Goldwater Institute point to the city of Phoenix's handling of "The Zone" encampment to show why the tax rebate is necessary.
- Cities have raised alarm bells about the initiative, saying it would take away resources that could otherwise be used to try to address shelter shortages and other long-term solutions to homelessness.
Prop. 314: Secure Border Act
The proposal would make it a state crime to cross into Arizona from Mexico anywhere except an official port of entry, a provision based on a similar law in Texas.
- It would require state and local governments to use federal systems to determine whether noncitizens are eligible to apply for public benefits.
- And it would impose stiff prison sentences for selling fentanyl that causes someone's death.
Go deeper:
- Measure making illegal border crossing a state crime will go to the ballot
- Speaker Toma believes he has the votes to pass border plan after Senate approval
Prop. 479: Regional transportation tax extension
This ballot proposition would extend a half-cent sales tax for regional transportation projects.
- The tax has been in place since 1985 and has supported the development of Loops 101, 202 and 303, the light rail and several other projects.
Go deeper:
Prop. 486: Maricopa County Community College District funding
The measure would permanently raise the spending cap formula imposed on the county's community college district by the Arizona Constitution.
- It would allow the district to spend more of the money it raises but wouldn't raise taxes.

Competitive state legislative races
- LD2: Incumbent Sen. Shawnna Bolick (R-Phoenix) faces Rep. Judy Schwiebert (D-Phoenix) in this competitive but Republican-leaning north Phoenix district.

- LD4: Sen. Christine Marsh (D-Phoenix) is looking to fend off Republican challenger Carine Werner, while incumbent Rep. Matt Gress (R-Phoenix) and Republican Pamela Carter face Democrats Karen Gresham and former Rep. Kelli Butler.
- LD9: Democrats hold all three seats in this west Mesa-based district, and keeping them will be critical if they hope to take control of the Legislature.
- LD13: This Chandler-based district may be Arizona's most competitive. Sen. J.D. Mesnard (R-Chandler) has fended off strong Democratic challenges before, while Democrats are making a rare play for both the district's House seats, but must do so without battle-tested Rep. Jennifer Pawlik (D-Chandler), who isn't seeking re-election.
- LD16: Rep. Keith Seaman (D-Casa Grande) faces a tough re-elect in this Republican-leaning Pinal County-based district, while Stacey Seaman, the lawmaker's daughter, takes on longtime Sen. T.J. Shope (R-Coolidge).
- LD17: Control of the Senate may run through this northern Tucson-area district, but former Sen. Vince Leach's win over Freedom Caucus Sen. Justine Wadsack (R-Tucson) in the GOP primary could hurt Democrats' chances in this Republican district. Democrats are also hoping to snag a House seat.
- LD23: Rep. Michele Peña (R-Yuma) blocked the Democrats from splitting the House in 2022 when she won a seat in this heavily Democratic district in southwestern Arizona. They'll need to win it back if they want control of the House.

- Wooten formerly served as the chief city prosecutor in Glendale and as a judge in Avondale, El Mirage, Mesa, Scottsdale, Surprise and Wickenburg.
Go deeper:
Maricopa County recorder: Timothy Stringham (D) vs. Justin Heap (R)
Republican state lawmaker Justin Heap defeated incumbent Recorder Stephen Richer and now faces Democrat Timothy Stringham.
- Heap is aligned and backed by many of the MAGA Republicans who have questioned the validity of Maricopa County's election results, and has declined to say whether President Biden legitimately won the 2020 election. He's a state representative and member of the Arizona Freedom Caucus who's critiqued the county's handling of elections.
- Stringham is a political newcomer and a veteran of the Army and Navy. He also served in the Judge Advocate General's Corps. He's attempting to appeal to anti-Trump Republicans who resent the election-denial rhetoric pushed by people associated with Heap's campaign.
