HD-44. Valerie Gaydos* (R) vs. Hadley Haas (D)

This 44th District seat may hold the key to the House majority moving forward. Gaydos, a three-term incumbent, touts herself as an independent, business-minded Republican. Haas, a marketing/communications professional, has out-fundraised her opponent which is no easy feat considering Gaydos’ incumbency. (WESA)

HD-72. Frank Burns* (D) vs. Amy Bradley (R)

Eight-term state representative Burns might be facing the toughest challenge of his career in Bradley. Burns has been able to win in a majority-Republican district and has negatively portrayed Bradley, the Cambria Regional Chamber president and CEO. Donald Trump and Project 2025 has been a major factor in the race. (Tribune-Democrat)

Although it is a D+22 district, the fact that the neighboring district (173) is represented by a Republican and a GOP rep also sits on City Council is worrisome to Dems. (DV Journal)
