Rep. Kyrsten Sinema raised $582,000 in the second quarter — a hefty sum as the freshman Democrat awaits her GOP opponent in Arizona’s 9th District.  

Sinema’s haul left her war chest at $1.59 million as of June 30, the last day of the second quarter.  

Two Republicans are running in the Aug. 26 primary: retired Air Force Officer Wendy Rogers and former Arizona State University quarterback Andrew Walter.  

Neither Rogers or Walter have released their second-quarter reports. But as of March 31, the last day of the first quarter, both were at a significant cash disadvantage to Sinema.  

Rogers reported $404,000 in the bank, and Walter had $256,000 in cash on hand.  

Republicans are targeting Sinema’s seat as pick-up opportunity. President Barack Obama carried the district by a 5-point margin in 2012.  

Arizona’s 9th District is rated as a Democrat Favored contest by Rothenberg Political Report/Roll Call.
