The 2024 election season is in full swing across the United States. Here’s when Arizonans can cast their votes in the Primary Election.

PHOENIX — Arizona is expected to play a critical role in the White House race, similar to its position in 2020. Tuesday’s state primaries will set the stage for key contests that could determine control of the U.S. Senate, U.S. House, and both chambers of the state legislature.

Here is everything you need to know before Arizona’s primary.

When is the Arizona Primary Election?

Arizona’s primary election will be held on Tuesday, July 30. Voting begins at 6 a.m. and will end at 7 p.m. The Navajo Nation observes daylight saving time, so polls there close at 6 p.m. Arizona time, affecting parts of three counties in the 2nd Congressional District.

Where can I vote?

A full list of polling places in Maricopa County is available. Pima County voters can find their polling location online. For questions about voting locations and hours, contact local election officials listed on the Arizona Secretary of State website.

Who is on the ballot for the Primary Election?

The Republican primary to replace U.S. Sen. Kyrsten Sinema is significant. Sinema, who became an independent in 2022, won’t seek a second term. U.S. Rep. Ruben Gallego is unopposed for the Democratic nomination. The Republican primary features Kari Lake, Pinal County Sheriff Mark Lamb, and neuroscientist Elizabeth Reye. Lake has received endorsements from ex-President Donald Trump.

In the U.S. House, Democrats aim to unseat two Arizona Republican incumbents in districts where Biden narrowly won in 2020. Rep. David Schweikert leads his Republican primary against Robert Backie and Kim George in the 1st Congressional District. The Democratic primary includes Andrei Cherny, Marlene Galán-Woods, Andrew Horne, Kurt Kroemer, Conor O’Callaghan, and Amish Shah.

Schweikert led in campaign fundraising. Cherny raised the most among Democrats until the end of June, with O’Callaghan having substantial funds due to a $905,000 loan to his campaign. Cherny has endorsements from ex-President Bill Clinton and Phoenix Mayor Kate Gallego. Galán-Woods is backed by ex-governor Janet Napolitano, state Attorney General Kris Mayes, and Rep. Raúl Grijalva.

In the 6th Congressional District, Rep. Juan Ciscomani faces Republican Kathleen Winn. If he wins, he’d face Democrat Kirsten Engel again, who received over 49% of votes against him in 2022.

Other primary challenges include first-term Republican Rep. Eli Crane in the 2nd District against Jack Smith. Republicans hold the majority in both state legislature chambers, with Democrats aiming to take over the Senate and House in the general election.

Tuesday’s primaries were moved from Aug. 6 to give counties more time to tally votes in case of an automatic recount. A full list of candidates is available online.

Who can vote in the Primary Election?

Registered party members vote only in their own party’s primary. Independents can participate in either primary. Maricopa County, home to Phoenix and neighboring cities, is a pivotal voting region. It contributed over 60% of the vote in the 2022 governor’s race, with Pima County being a distant second.

In state House primaries, voters select up to two candidates, and the AP declares two winners per contest. Write-in votes in the Republican primary for House District 29 may delay the winner’s announcement. The AP will only declare a winner when it’s clear the trailing candidate can’t close the gap. Recounts are automatic if the margin is 0.5% or less of the total vote.

What does turnout for the primaries look like?

As of April, nearly 4.1 million voters were registered in Arizona: 35% Republicans and 29% Democrats. In the 2022 midterms, turnout was 13% in Democratic and 18% in Republican primaries. Arizona’s “Active Early Voting List” sent mail ballots to eligible voters. By Tuesday, nearly 696,000 ballots had been cast early, with 45% for the Democratic primary and 54% for the Republican primary.

How long does vote-counting usually take?

In the 2022 midterm primaries, results first reported at 11:01 p.m. ET, one minute after polls closed. Election night tabulation ended at 7:11 a.m. ET, with 77% of votes counted.

Are we there yet?

As of Tuesday, there are 98 days until the November general election.
