Democrat James Malone has won an open Pennsylvania state Senate seat in a major upset in a district that comfortably voted for President Trump in November, Decision Desk HQ projects.

Malone, the mayor of East Petersburg, is projected to defeat Republican Lancaster County Commissioner Josh Parsons to represent Senate District 36 for the remainder of former state Sen. Ryan Aument’s (R) term. Aument resigned from his office in December to become the state director for McCormick, who took office in January.

Parsons was considered likely to win in the conservative-leaning district, which President Trump carried in November with 57 percent of the vote and McCormick won with 56 percent. Aument had even been unopposed in his last election in 2022.

But Malone was able to overcome the odds, and the Democratic Party continued its strong performance in under-the-radar elections since Trump took office. Democrats notched another major upset in a strongly conservative Iowa state Senate district in January, also winning a county executive seat in New York, among other more low-key successes.

Democratic National Committee Chair Ken Martin celebrated Malone’s victory, calling it a “shockwave” to the system and the way Republicans have run the government.

“In a district that went to Trump by 15 in 2024 and has a 23-point Republican voter registration advantage, Malone’s victory is a loud and clear rebuke to Republicans’ threats to the programs Pennsylvania families rely on – from Social Security and Medicaid to our public schools,” Martin said.
