2018 Pennsylvania elections

The 2018 Pennsylvania state elections took place on November 6, 2018. On that date, the Commonwealth of Pennsylvania held elections for the following offices: Governor and Lieutenant Governor (on one ticket), U.S. Senate, U.S. House of Representatives, Pennsylvania State Senate, Pennsylvania House of Representatives, and various others. Primary elections took place on May 15, 2018.

Background
On Election Day, Democratic Gov. Tom Wolf was re-elected with new Lt. Gov. John Fetterman, as was incumbent Democratic U.S. Senator Bob Casey Jr. Democrats gained five seats in Pennsylvania's congressional delegation, bringing the delegation to a 9–9 split. Democrats also broke a Republican supermajority in the Pennsylvania State Senate by gaining five seats, and gained eleven seats in the Pennsylvania House of Representatives.

United States Senate
Incumbent Democratic Senator Bob Casey Jr. sought reelection against Republican Congressman Lou Barletta in the general election. He won with 56% of the vote.

Redistricting
In January 2018, the Pennsylvania Supreme Court struck down the state's congressional map, ruling it had been unfairly gerrymandered to favor Republicans. New maps were subsequently adopted in February 2018, for use in 2018's elections and taking effect with representation in 2019.

A special election for Pennsylvania's 18th congressional district was held on March 13, 2018, following the resignation of Republican Rep. Tim Murphy.

Along with the general election, special elections were also held on November 6, following the resignations of Republican Reps. Pat Meehan (PA-7) and Charlie Dent (PA-15).
