1860 United States presidential election in Pennsylvania

A presidential election was held in Pennsylvania on November 6, 1860, as part of the 1860 United States presidential election. The People's ticket of the former U.S. representative from Illinois's 7th congressional district and the senior U.S. senator from Maine Hannibal Hamlin defeated the Fusion ticket nominated by the Pennsylvania Democratic Party.

Lincoln was nominated by the 1860 Republican National Convention and ran as the candidate of the People's Party in Pennsylvania. Formed in 1858, the party united Pennsylvania Republicans and Know Nothings on a protectionist platform that appealed to antislavery and nativist constituencies in both parties. The Pennsylvania Democratic party selected its state ticket in advance of the 1860 Democratic National Conventions, which resulted in a split between the supporters of Stephen A. Douglas and John C. Breckinridge. The so-called "Reading ticket," named after the city in Pennsylvania where the state convention met, was composed of 15 Breckenridge supporters and 12 Douglas supporters; the electors agreed to vote for whichever candidate stood the best chance of defeating Lincoln in the event the fusion ticket carried the state. A minority of Douglas Democrats in Pennsylvania opposed this arrangement and nominated their own ticket of 27 candidates, including the 12 Douglas electors on the Reading ticket. The split in the Democratic ranks effectively conceded the state to Lincoln, ending fears that the defection of protectionist voters to the Constitutional Union Party could cost Republicans the state's 27 electoral votes.
