Arizona Legislative District 28 covers a suburban stretch of northwest Maricopa County that takes in parts of Peoria, Surprise, Glendale, and the retirement communities of Sun City and Sun City West. Like every Arizona legislative district, it sends one state senator and two state representatives to the Capitol, and all three current seats are held by Republicans.
Where the District Sits
LD 28 is in the northwest Phoenix metro area. The current boundaries were adopted by the Arizona Independent Redistricting Commission on January 21, 2022, and will remain in place until new maps are drawn after the 2030 Census.1Arizona Independent Redistricting Commission. Maps

The Electorate and Why the Primary Matters
As of the July 2024 registration report, LD 28 had about 158,564 active registered voters. Republicans made up roughly 47.9%, voters with no party or a minor party about 30.1%, and Democrats about 22.0%.9Arizona Secretary of State. State Voter Registration Report – July 2024
With Republican registration running close to two to one over Democratic registration, the competitive race for an LD 28 seat is normally the Republican primary rather than the general election. If you want a say in who represents the district, the primary is usually where that choice gets made.

How the Map Was Drawn
Arizona’s legislative lines are drawn by the Arizona Independent Redistricting Commission, a five-member body created by the state constitution with no more than two members from any single political party. It redraws both congressional and legislative maps after each decennial census, working from a grid of equally populated districts and then adjusting to meet six ranked constitutional goals: federal law compliance, equal population, compactness and contiguity, communities of interest, visible geographic boundaries, and competitiveness.11Arizona Legislature. Arizona Constitution Article 4 Part 2 Section 1
Competitiveness sits last on that list, and the commission is not required to pursue it at the expense of the higher-ranked goals. That is one reason districts like LD 28 can be reliably safe for one party.
