After several cycles of hard-won gains, Pennsylvania Democrats seized a historic opportunity to expand their majority in the state House and FLIP the state Senate in the 2026 midterm elections. 

After flipping the Pennsylvania House in 2022, the DLCC and state Democrats built on years of hard work, establishing a new legislative trifecta in the Keystone State for the first time in over 30 years.

These 2026 victories put Democrats in a position to end years of legislative gridlock, fight back against Trump’s disastrous agenda, and usher in a new era of progress for Pennsylvanians.
