Arizona picked up a fifth district as a result of theredistricting cycle after the1980 census. It covered most of the southeastern portion of the state, though the bulk of its population was located in the eastern half ofTucson. It was a Republican-leaning swing district, though a Democrat won it when it was first contested in 1982 before giving way to a Republican in 1984.
After the 2000 census, this district essentially became the8th district, while most of the Maricopa County portion of the old6th district became the new 5th district. This version of the 5th covered all ofTempe andScottsdale and portions ofChandler,Mesa and theAhwatukee section ofPhoenix. Although Republicans outnumbered Democrats by about 40,000 voters, the 5th district was considered far less conservative than other suburban Phoenix districts.George W. Bush received 54% of the vote in this district in2004 and home state candidateJohn McCain narrowly won the district in2008 with 51.70% of the vote whileBarack Obama received 47.17%.
After the 2010 census, this district mostly became the9th district, while the 5th was reconfigured to take in most of the East Valley. This area had previously been the1st district from 1951 to 2003 and the 6th district from 2003 to 2013. Like its predecessors, this district was heavily Republican.
After the 2020 census, this district, and the West Valley-based 8th, were the only two districts to remain in substantially the same areas. The revised 5th district still covers part of easternMaricopa County and northernPinal County, includingApache Junction. In Maricopa County it is basically south of downtownPhoenix and theSalt River and east ofRt. 101. It is the only Valley-based district that does not include any of Phoenix itself..[4]
