The race for Matt Salmon's Congressional seat remains a party of one.
Gov. Doug Ducey's Chief of Staff, Kirk Adams, said in a Facebook post Monday that he has "decided to continue serving where I am, and leave the race for AZ Congressional District 5 to others."
Adams was regarded as a potential candidate when Salmon announced last week that he won't be seeking re-election this coming November. He ran against Salmon in the 2012 Republican primary.
State Senate President Andy Biggs, who announced his bid with Salmon as his campaign chairman, is the only candidate in the race thus far.
Biggs has also picked up endorsements from Phoenix City Councilman Sal DiCiccio and U.S. Rep. Trent Franks.
Salmon's district is largely GOP. It spans the Southeast Valley and includes Mesa, Chandler and Gilbert.
The state filing period for Salmon's seat runs from May 2 through June 1.
Chandler Mayor Jay Tibshraeny, State Rep. Bob Robson (R-Chandler), former Mesa Mayor and Interim Valley Metro CEO Scott Smith and State Sen. Bob Worsley (R-Mesa) are also considering runs.
