Background Prior to the ratification of the Seventeenth Amendment in 1913, U.S. Senators were elected by state legislatures rather than by popular vote. In Pennsylvania, the Pennsylvania General Assembly, comprising the House of Representatives and the Senate, convened to elect senators. The 1806 election was for the Class 3 seat, with the term beginning on March 4, 1807, and ending on March 3, 1813. Election process The Pennsylvania General Assembly convened on December 9, 1806, in Lancaster, Pennsylvania, the state capital at the time, to elect a U.S. Senator for the term beginning March 4, 1807. The election required a majority of votes from the combined houses, as per federal law governing Senate elections. Four ballots were conducted over several days. The candidates were: Andrew Gregg, a former U.S. Representative (1791–1807) and a prominent Democratic-Republican. Nathaniel Boileau, a lesser-known Democratic-Republican with support from certain factions. Isaac Weaver Jr., another Democratic-Republican candidate with limited backing. After three inconclusive ballots, the fourth and final ballot on December 16, 1806, resulted in a clear majority for Gregg. Results The results of the fourth and final ballot, combining votes from both houses of the Pennsylvania General Assembly, are as follows: Candidate Party Votes Percentage Andrew Gregg Democratic-Republican 68 60.71% Nathaniel Boileau Democratic-Republican 34 30.36% Isaac Weaver Jr. Democratic-Republican 6 5.36% Others — 4 3.57% Total 112 100.00% Aftermath Andrew Gregg was elected to the U.S. Senate and served from March 4, 1807, to March 3, 1813. His tenure was marked by his support for Jeffersonian policies, including trade restrictions and preparations for the War of 1812. Notably, Gregg was elected President pro tempore of the United States Senate in 1809, serving briefly during the 11th United States Congress.
