Pennsylvania ratified the United States Constitution on December 12, 1787, and elects its U.S. 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.S. 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).

U.S. senator from Pennsylvania in the context of James Buchanan
James Buchanan Jr. (/bjuːˈkænən/ bew-KAN-ən; April 23, 1791 – June 1, 1868) was the 15th president of the United States, serving from 1857 to 1861. He also served as the secretary of state from 1845 to 1849 and represented Pennsylvania in both houses of the U.S. Congress. Buchanan was an advocate for states' rights, particularly regarding slavery, and minimized the role of the federal government preceding the American Civil War.
Buchanan was a lawyer in Pennsylvania and won his first election to the state's House of Representatives as a member of the Federalist Party. He was elected to the U.S. House of Representatives in 1820 and retained that post for five terms, aligning with Andrew Jackson's Democratic Party. Buchanan served as Jackson's minister to Russia in 1832. He was elected a U.S. senator from Pennsylvania in 1834 and served for 11 years. He was appointed to serve as President James K. Polk's secretary of state in 1845, and eight years later was named as President Franklin Pierce's minister to the United Kingdom.
