TUCSON, Ariz. (AP) — Former Surgeon General Richard Carmona no longer looks to be the only candidate in Arizona’s Democratic primary for U.S. Senate.
The Arizona Daily Star reports Tucson psychiatrist David Ruben has gathered enough signatures before the Wednesday deadline to be on the ballot Aug. 28.
Ruben submitted more than 7,000 signatures last week. The minimum required is 5,671.
Ruben has raised $300 for his campaign through March. Records show Carmona has raised $1.3 million in the same amount of time.
The 64-year-old says his experience talking to people throughout his 35-year psychiatry career has helped prepare him for a Senate run.
Pima County elections officials say Ruben has switched party affiliations several times over the last three decades. He has been both an independent and a Republican.
