The 2018 Pennsylvania gubernatorial election took place on November 6, 2018, to elect the Governor and Lieutenant Governor of Pennsylvania, concurrently with the election of Pennsylvania's Class I U.S. Senate seat, as well as elections to the United States House of Representatives and various local elections. Incumbent Governor Tom Wolf won re-election to a second term by a double-digit margin, defeating Republican challenger Scott Wagner and two third-party candidates from the Green Party, Paul Glover and Libertarian Party, Ken Krawchuk. The primary elections were held on May 15. This was the only Democratic-held governorship up for election in a state that Donald Trump won in the 2016 presidential election.
Republicans flipped the counties of Lawrence, Greene, Fayette, Cambria, Clinton, Northumberland, Carbon, and Schuylkill. Meanwhile, this was the first time since Bob Casey Jr.'s landslide State Treasurer win in 2004 that Cumberland County voted for the Democrat in a statewide election.
