In Arizona politics, state-level candidates and PACs spent $63.7 million between Jan. 1, 2021, and Mar. 31, 2022. More than $20.1 million or 31.6 percent of all campaign finance expenditures went to the 10 payees at the top of the list. 

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.
