The 1948 United States presidential election in Pennsylvania took place on November 2, 1948 as part of the 1948 United States presidential election. Voters chose 35 representatives, or electors to the Electoral College, who voted for president and vice president.
Pennsylvania voted for the Republican nominee, New York Governor Thomas E. Dewey, over the Democratic nominee, President Harry S. Truman. Dewey won Pennsylvania by a margin of 4.01%. As of the 2024 presidential election, this is the last time that a Democrat won the national election without carrying Pennsylvania, although in 2016, Democrats won the national popular vote without the state.
This is the last time any candidate of either party won Pennsylvania without carrying Northampton County, and the last time a Republican won Pennsylvania without carrying neighboring Ohio. Pennsylvania weighed in for this election as 8.51% more Republican than the nation-at-large. This was the last time Pennsylvania voted to the right of the national environment until 2016.
