Pennsylvania was one of 11 states with a divided government ahead of the general elections. Democrats controlled the governorship and the state House, while Republicans controlled the state Senate. The state had a divided government since 2015. The last time the state had a Democratic trifecta was in 1993, and the last time it had a Republican trifecta was in 2014. Ballotpedia assessed a moderate possibility of either party gaining a trifecta as a result of the 2026 general elections.

Heading into the 2026 elections, Spotlight PA’s Stephen Caruso, wrote that since Democrats won control of the House in 2022, lawmakers had "struggled to advance far-reaching legislation on energy, transportation, or health care. Even passing a statutorily required budget to fund schools, counties, and nonprofits proved to be a challenge.” Caruso listed the Lehigh Valley, Northeast Pennsylvania, and western coal country as the most competitive parts of the state for the House.

Both the Democratic Legislative Campaign Committee (DLCC) and the Republican State Leadership Committee (RSLC) targeted the Pennsylvania General Assembly in the 2026 general elections.

The Democratic Legislative Campaign Committee (DLCC) targeted 18 House seats, including 10 the Democrats already held. The Republican State Leadership Committee (RSLC) targeted nine House seats, including seven the Republicans already held.
