Stacy Garrity, Pennsylvania's two-term elected state treasurer, said Monday that she will seek the Republican nomination to challenge Democratic Gov. Josh Shapiro's reelection bid, setting up what could be a contest between a low-profile officeholder and a potential White House contender in 2028.

Pennsylvania's governor contest is off to the races with its first challenger: state Treasurer Stacy Garrity. Why it matters: On Monday, the Republican announced her intention to unseat incumbent Democratic Gov.

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.
