The deadline for submitting nominations for Congress in Arizona this year was April 4, 2022. Thirty-nine candidates are running in the nine US House districts in Arizona, including 10 Democrats and 29 Republicans. That’s 4.33 candidates per constituency, more than the 4.22 candidates per constituency in 2020 and the 4.11 in 2018.
Here are some other highlights from this year’s filings:
- This is the first election to be held under new district lines after the 2020 census. Arizona was split into nine districts, the same number it was split after the 2010 census.
- The 39 candidates running this year are the most contenders for U.S. House seats from Arizona since at least 2014, the first year for which we have data.
- A district – the 6th – is open. This is one more than in 2020 and one less than in 2018.
- Representative David Schweikert (R), who represents the 6th arrondissement, is running in the 1st arrondissement this year. Rep. Tom O’Halleran (D), who represents the 1st District, is running in the 2nd District, where outgoing Rep. Ann Kirkpatrick (D) is retiring.
- The 2nd and 6th arrondissements attracted the most candidates this year, with eight candidates running each.
- There are eight primaries contested this year – two Democrats and six Republicans. This is the fewest contested primaries since 2014, when there were five contested primaries.
- Six incumbents — four Democrats and two Republicans — face no primary challenger.
- The 8th and 9th districts are guaranteed to Republicans because no Democrats have shown up to run. No district is guaranteed to Democrats because no Republicans have filed.
Arizona and four other states – Kansas, Michigan, Missouri and Washington – are holding primaries on August 2. The winners of the Arizona primaries are determined by plurality voting, which means the candidate with the most votes wins even if they didn’t. win an absolute majority of the votes cast.
