Despite not officially announcing as a candidate, Vernon Parker led the GOP field in Arizona’s 9th Congressional District primary fundraising.

Former Arizona State University quarterback Andrew Walter formed a campaign committee for a run in Arizona’s 9th Congressional District, giving first-term Democratic Congresswoman Kyrsten Sinema a potential Republican challenger with a built-in base of support among the Sun Devil faithful.
