Shapiro starts re-election campaign in Pennsylvania
Gov. Josh Shapiro announced his re-election campaign at the 6th Man Center in Nicetown, where he addressed a packed crowd of supporters. Shapiro emphasized his commitment to being a governor for all Pennsylvanians, focusing on issues like job creation, tax cuts, and education.
Big picture view:
Gov. Josh Shapiro is seeking reelection in 2026, and is running uncontested in Tuesday's primary. He's focused heavily on infrastructure, economic development and abortion rights in his first term.
A Quinnipiac University poll from February shows Shapiro has a 56% approval rating, with 40% of Pennsylvania voters even saying he would make a good President.
Shapiro is set to face Republican Stacy Garrity in November. Garrity is also running virtually unopposed in the primary. Her campaign has focused on fiscal issues, government accountability and public safety.

1st District Democratic Primary
Bucks County commissioner Bob Harvie and math PhD Lucia Simonelli competed for what's seen as a competitive District 1.

Dauphin County Commissioner Justin Douglas and former TV news anchor Janelle Stelson were in the fight for Pennsylvania's 10th District which serves the Harrisburg and York areas.
Stelson took home the Democratic Primary seat for the 10th District, Tuesday night, AP says.
Douglas has campaigned on a progressive platform focused on health care, labor rights and economic fairness, according to his campaign website. Stelson's campaign has centered on protecting abortion rights, defending democracy and lowering costs for families.
Stelson winner will look to unseat Republican Scott Perry in November. Perry has represented the district since 2013.
State House's 100th District's Republican Primary
Pennsylvania's 100th State House District covers part of Lancaster County, and has been represented by former Speaker of the Pennsylvania House Bryan Cutler since 2006.
With Cutler choosing not to seek reelection in 2026, Lancaster County businessman Dave Nissley and retired Pennsylvania State Police master trooper Kelly Osborne are looking to take his seat.
Nissley proposes eliminating property tax and "unnecessary and often redundant regulations, codes, and laws," advocating for parental choice and more. Osborne's platform similarly prioritizes limited government, no tax increases, and parental rights.
Currently, Democrats hold a one-seat majority in the Pennsylvania State House. All 203 seats are up for election in November.
