Pennsylvania has a divided government, and no political party holds a state government trifecta. A trifecta exists when one political party simultaneously holds the governor’s office and majorities in both state legislative chambers. Heading into the special elections, Republicans hold a 26-22 majority in the state Senate with two vacancies. The state House is controlled by a 109-93 Republican majority with one vacancy. Gov. Tom Wolf (D) was first elected in 2014 and won re-election to a second term in 2018.
