Nominating signatures are in! Ballots are almost set.

I say "almost" because there will be (inevitably) legal challenges to some candidacies and some candidate withdrawals.

Legal challenges and withdrawals are here.

TJ L'Heureux, writing for Arizona Agenda, has a solid primer on challenges here.

I will add something about challenges -challenges usually (but not always) come from primary opponents, but not from a candidate directly..  Usually, a proxy is used.  One challenge is from Steve Slaton, a 2024 candidate in LD7.  He's filed one against Rep. Walt Blackman.

L'Heureux writes about possible hard feelings between the two stemming from Slaton's loss in 2024.

However, Slaton and State Sen. Wendy Rogers are staunch allies, and Rogers and Blackman don't like each other.  As such, while there are almost certainly some hard feelings, Slaton almost as certainly is acting as a surrogate for Rogers.

A few definitions/caveats about the following list:

Under "Party", the abbreviation indicates the party of the candidate that is listed on the website of the Arizona Secretary of State - "Rep" = Republican, "Dem" = Democrat; "Grn" = Green; "NL" = No Labels, though some folks may have signed petitions for candidates of the Arizona Independent Party; and "Lbt" = Libertarian.

Risa Lombardo is listed as a Green Party candidate, though she's a Green the same way I'm a Yankees fan (I'm not).

The listing order in each grouping of candidates (statewide and Congressional) was decided by the AZSOS. 

Also, I didn't include legislative races in the list; there were just too many candidates.

A few observations:

In a surprise that isn't really much of surprise, Gina Swoboda, a former chair of the Arizona Republican Party, turned in enough sigs to be on the ballot and mount a primary challenge to Alexander Kolodin, currently a state legislator.  It was a bit of a surprise because she jumped into that race in early February (I think).

Nick Mansour has a primary opponent in the R primary for AZ Treasurer in the person of Katherine Haley.  For the longest time, he was alone in race and it looked like he would buy the nomination unopposed.

In the "I truly expected this primary to be bigger" category is R primary in CD5.  The only two Rs in that race are Daniel Keenan and Mark Lamb.  Cheeto has endorsed Lamb, and that may have scared off some other potential candidates (it scared Jay Feely into the CD1 race, which in turn scared Swoboda into the AZSOS race); however, openings in "safe" Congressional seats are rare and usually attract more candidates, Cheeto notwithstanding.

In the "back for more?" category is Republican Daniel Francis Butierez, Sr. in CD7.  In 2025, he lost/was thoroughly trounced  by Adelita Grijalva.
