List of United States senators from Pennsylvania
Updated: 5/20/2026, 8:10:57 PM Wikipedia source
Pennsylvania ratified the United States Constitution on December 12, 1787, and elects its U . senators to class 1 and class 3. Officeholders are popularly elected, for a six-year term, beginning January 3. Elections are held the first Tuesday after November 1. Before 1914, they were chosen by the Pennsylvania General Assembly; before 1935, their terms began March 4. The state's current U . senators are Democrat John Fetterman (since 2023) and Republican Dave McCormick (since 2025), making it one of four states to have a split Senate delegation, along with Maine, Vermont, and Wisconsin. Arlen Specter was Pennsylvania's longest-serving senator (1981–2011).
