The Arizona Secretary of State has released the registration tally as of January 1, 2024. See it here. Percentages are: Republican 34.58%; Democratic 29.55%; Independent and miscellaneous 34.38%; Libertarian .79%; No Labels .63%; Green .06%.
As the October 2023 tally, the percentages had been: Republican 34.33%; Democratic 29.76%; independent and miscellaneous 34.59%; Libertarian .80%; No Labels .45%; Green .08%.
The January 1 tally of election years determines the number of signatures needed for statewide independent candidates, .3% of the number of registered voters who are not in a qualified party. We can now know that the 2024 independent requirement will be exactly 42,303.
No Labels registration is growing so rapidly, it seems very likely that it soon will have enough registrations to remain on the ballot into years beyond 2024. To stay on the ballot a party needs registration of two-thirds of 1% of the state total. Thanks to Eric Wong for the news about the new tally being released.
