Pennsylvania Treasurer Stacy Garrity will seek the Republican nomination to challenge Gov. Josh Shapiro's reelection bid in 2026.

State GOP leaders are expected to throw their support behind Garrity. Many of them are worried about a second run from state Sen. Doug Mastriano.

The Pennsylvania Republican Party plans to endorse a candidate for governor in September — nearly half a year earlier than in the past — in an attempt to learn from its 2022 losses and capitalize on its 2024 successes.
