The Arizona Secretary of State has posted registration data for July.  See it here.

The percentages are:  Republican 35.39%; Democratic 28.11%; No Labels 1.07%; Libertarian .71%; Green .12%; independent and other 34.60%.

At the April 2026 tally, the percentages had been:  Republican 35.54%; Democratic 28.13%; No Labels 1.03%; Libertarian .71%; Green .12%; independent and other 34.48%.

No Labels is only the second minor party in Arizona history to have enough registrations to automatically stay on the ballot.  The first such party was the Libertarian Party.  So it seems inevitable that No Labels will still be a qualified party in Arizona in 2028.
