HARRISBURG — Pennsylvania Gov. Josh Shapiro is running for a second term in the pivotal battleground state after a first term that put him on the Democratic Party’s radar as a potential presidential contender in 2028.

He made the formal announcement Thursday, Jan. 8, at an event at a carpenters’ union hall in Pittsburgh and was to appear later at a similar event in Philadelphia. Shapiro’s announcement demonstrated a unified party behind him — including introductions by the state party chairman, labor leaders and top local Democratic officials — as he ticked off his accomplishments during a nearly 30-minute speech.

Shapiro warned that his opponents promise “darkness and division and extremism,” and — without mentioning President Donald Trump by name — he slammed the “chaos and toxicity” emanating from Washington, D.C., that he said threatened livelihoods, rights and freedoms.

“Every step of the way, I’ve stood up for my fellow Pennsylvanians, sometimes in a court of law and other times simply refusing to back down, refusing to cast certain Pennsylvanians aside and always by speaking truth to power,” Shapiro said.

He added, “I will not let anyone mess with Pennsylvania, and I will always have your backs.”

Although Shapiro hasn’t disclosed any ambitions for higher office, his reelection effort will be closely watched as another test of whether he’s White House material.

Ever since he won the governor’s office in a near-landslide victory in 2022, Shapiro has been mentioned alongside Democratic contemporaries like California Gov. Gavin Newsom, Illinois Gov. JB Pritzker, Maryland Gov. Wes Moore and others as someone who could lead a national ticket.

Shapiro, 52, has already made rounds outside Pennsylvania. Last year, he campaigned for Democrats running for governor in New Jersey and Virginia, and he’s a frequent guest on Sunday talk shows that can shape the country’s political conversation.

He was also considered as a potential running mate for Kamala Harris in 2024. She chose Minnesota Gov. Tim Walz instead.

In the upcoming Pennsylvania Governor race, Shapiro will retain Lt. Gov. Austin Davis as his running mate.

He’s expected to run against GOP candidate and state treasurer Stacy Garrity, who has campaigned around Pennsylvania and spoken at numerous Trump rallies in the battleground state, but she will have to contend with her relatively low profile as compared to Shapiro.

Shapiro’s first term repeatedly put him in the spotlight.

He was governor when an attempt was made on Trump’s life during a rally in Butler County; for the capture of Luigi Mangione for allegedly killing United Healthcare chief executive Brian Thompson; and for the murder of three police officers in York County.

Last year, an arsonist tried to kill Shapiro by setting the governor's official residence on fire in the middle of the night. Shapiro had to flee with his wife, children and members of his extended family, and the attack made him a sought-out voice on the nation’s recent spate of political violence.

As Shapiro settled into the governor’s office, he shed his buttoned-down public demeanor and became more plain-spoken.

He pushed to quickly reopen a collapsed section of Interstate 95 in Philadelphia, debuting his new and profane governing slogan — “get (expletive) done” — at a ceremony for the completed project.

He crossed the partisan divide over school choice to support a Republican-backed voucher program, causing friction with Democratic lawmakers and allies in the state.

Shapiro regularly plays up the need for bipartisanship in a state with a politically divided Legislature, and positions himself as a moderate on energy issues in a state that produces the most natural gas after Texas.

He's rubbed elbows with corporate executives who are interested in Pennsylvania as a data center destination and thrust Pennsylvania into competition for billions of dollars being spent on energy, manufacturing and artificial intelligence.

In a September appearance on NBC News’ “Meet the Press,” the host, Kristen Welker, asked Shapiro whether he’d commit to serving a full second term as governor and whether he’d rule out running for president in 2028.

“I’m focused on doing my work here,” he said, sidestepping the questions.

His supposed White House aspirations — which he’s never actually admitted to in public — are also mentioned frequently by Garrity.

“We need somebody that is more interested in Pennsylvania and not on Pennsylvania Avenue,” Garrity said recently on a radio show in Philadelphia. On Thursday, the Republican Governors Association accused Shapiro of being “more focused on his political ambitions” than leading Pennsylvania.

For his part, Shapiro criticizes Garrity as too eager to get Trump’s endorsement to be an effective advocate for Pennsylvania.

In any case, the campaign trail could afford Shapiro an opportunity to audition for a White House run.
