Arizona's 9th congressional district

Arizona's 9th congressional district is a United States congressional district located entirely within Maricopa County. The district is anchored in the urban core of the Phoenix metropolitan area, encompassing parts of the cities of Phoenix, Tempe, Mesa, and Chandler. It is currently represented by Democrat Greg Stanton, a former mayor of Phoenix.

History

The district was created following the 2010 Census, which granted Arizona an additional House seat. It was first contested in the 2012 elections. The district's boundaries were drawn by the Arizona Independent Redistricting Commission and have been subject to minor adjustments after the 2020 Census. Historically, the area has been a political battleground, though it has trended increasingly toward the Democratic Party in recent election cycles. Key landmarks within the district include Sky Harbor International Airport, Arizona State University, and the Salt River Pima-Maricopa Indian Community.

Election results

In its inaugural election, Democrat Kyrsten Sinema narrowly defeated Republican Vernon Parker in 2012. Sinema was re-elected in 2014 and 2016 before vacating the seat to run successfully for the United States Senate. The subsequent 2018 election saw Democrat Greg Stanton win the open seat, defeating Republican Steve Ferrara. Stanton has since been re-elected in 2020 and 2022. The district's Cook Partisan Voting Index currently rates it as D+4.

Demographics

The district is one of the most densely populated and diverse in Arizona. According to the U.S. Census Bureau, the population is approximately 794,680. A significant portion of residents hold a bachelor's degree or higher, driven by the presence of Arizona State University. The ethnic composition is diverse, with a substantial Hispanic population alongside non-Hispanic White, Asian, and Black communities. The district is overwhelmingly urban, with major employment centers in downtown Phoenix, the Tempe Town Lake area, and the Mesa Gateway region.

Recent elections

In the 2022 midterm elections, incumbent Greg Stanton defeated Republican nominee Kelly Cooper, a former Marine. The race was called by the Associated Press shortly after polls closed. The 2020 election saw Stanton easily overcome a challenge from Republican Dave Giles. These results reflect the district's leftward shift, contrasting with closer margins in the early 2010s. Upcoming contests will be influenced by national political trends and local issues such as water policy, infrastructure, and higher education funding.
