Arizona is holding a special election for the vacant Seventh District U.S. House seat on September 23, 2025. Each qualified party had its own special primary on July 15, 2025. The Green Party and the No Labels Party each nomianted someone by write-in vote in their own primaries. The Libertarian Party also had a write-in candidate in its primary, but the person who got the most votes in the Libertarian primary can’t be on the September 23 ballot because the rules are different for the Libertarian Party.
The Green Party and the No Labels Party each petitioned in 2024, so they are considered “new” parties. “New” parties can nominate by write-in very easily. Whoever gets the most votes in their primaries is nominated, regardless of how few write-ins they received. The Green Party winner got 42 write-ins and the No Labels Party candidate got one write-in.
But the Libertarian Party is not considered a new party, because it has been continuously qualified since 2000. So write-in candidates in its primary need a large number of write-ins to be nominated.
Here are the election results for the July 15, 2025 primary.
