Bob Casey Jr., U.S. Senator from Pennsylvania, served from 2007 to current. He has built a reputation as a moderate Democrat focused on healthcare, labor rights, and support for working families. Known for his bipartisan approach, Casey was a strong advocate for the Affordable Care Act, Medicaid expansion, and children’s health programs like CHIP. He also championed labor rights, advocating for fair wages and worker protections in Pennsylvania’s large industrial and union communities. Despite his commitment to these issues, Casey faced criticism for his support of certain Democratic policies, particularly around environmental regulation and healthcare mandates. In 2024, he narrowly lost his re-election bid to Republican David McCormick, signaling a shift in Pennsylvania’s political landscape.
