Arizona Senate race pits Lieberman against Werner over Medicaid fraud record
Democrat Aaron Lieberman is challenging Republican Sen. Carine Werner in Arizona's Legislative District 4, a competitive seat covering parts of Phoenix, Scottsdale and Paradise Valley, in the November general election. Lieberman, a former state representative, is campaigning on pragmatism and bipartisanship, targeting independents and moderate Republicans. Werner, who chairs the Senate Health and Human Services Committee, sponsored 21 bipartisan bills signed by Gov. Katie Hobbs, many focused on preventing Medicaid fraud, protecting healthcare workers, and reforming Department of Child Safety communications following the 2025 murder of Emily Pike. Lieberman argues Werner's broader record, including advocacy for PragerU content in schools, makes her too extreme for the swing district.
