In Arizona, state-level candidates have spent $100 million between Jan. 1, 2021, and Oct. 22, 2022. Democratic candidates have spent $29.8 million and Republican candidates have spent $69.8 million. 

Arizona politics became a battleground of national interest during the contentious tabulation of 2020 election results. While it’s state-level races may not have pulled in quite the volume of outside money that other highly-publicized battlegrounds drew, Arizona elections still managed to attract some major nationwide donors.
