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.
Incumbent Democratic Senator Bob Casey Jr. sought reelection against Republican Congressman Lou Barletta in the general election. He won with 56% of the vote.
In January 2018, the Pennsylvania Supreme Court struck down the state's congressional map, ruling it had been unfairly gerrymandered to favor Republicans.[1][2] New maps were subsequently adopted in February 2018, for use in 2018's elections and taking effect with representation in 2019.[3]
A special election for Pennsylvania's 18th congressional district was held on March 13, 2018, following the resignation of Republican Rep. Tim Murphy.[4]
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).
