Republicans hope the victor of a 3-way primary will flip a Phoenix congressional district full of independent voters come November, but with a former mayor waiting, Democrats think they will keep it.
Arizona's 9th Congressional District seat is held by Democratic Rep. Kyrsten Sinema, but she's running to succeed Republican Sen. Jeff Flake. Looking to keep the House district blue is former Phoenix mayor Greg Stanton, who is unopposed in Tuesday's primary.
Former Navy chief medical officer Steve Ferrara, returning candidate David Giles and Irina Baroness Von Behr are vying in the Republican primary. The winner meets Stanton in November.
Former Democratic Congressional Campaign Committee chair Steve Israel says the district is likely a keeper for Democrats.
The district went for Hillary Clinton in 2016, but it has more unaffiliated voters than Republicans or Democrats.
