ENOLA, Pa. (AP) — Democratic Sen. John Fetterman of Pennsylvania isn’t even up for reelection until 2028, but already a one-time primary foe, former U.S. Rep. Conor Lamb, is crisscrossing Pennsylvania and social media, looking and sounding like he’s preparing to challenge Fetterman again.

At town hall after town hall across Pennsylvania, Democrats and allied progressive groups aren’t hearing from Fetterman in person — or Republicans who control Washington, for that matter.

But they are hearing from Lamb, a living reminder of the Democrat they could have elected instead of Fetterman. The former congressman has emerged as an in-demand town hall headliner, sometimes as a stand-in for Fetterman — who just might bash Fetterman.

“I thought I was going to play Senator Fetterman,” Lamb joked as he sat down in front of a central Pennsylvania crowd last Sunday.

Democrats are frustrated with Fetterman

Lamb’s reemergence comes at an in-between moment, roughly halfway through Fetterman’s six-year term, and is helping define the struggle facing Democrats in swing-state Pennsylvania.

There, Democrats figure prominently in their national effort to push back on President Donald Trump, but also in their struggle to figure out what to do about Fetterman, who is under fire from rank-and-file Democrats for being willing to cooperate with Trump.

Frustration with Fetterman has been on display on social media, at the massive “ No Kings ” rally in Philadelphia and among the Democratic Party’s faithful. The steering committee of the progressive organization Indivisible PA last month asked Fetterman to resign.

It’s quite a turnabout for the hoodies-and-shorts-wearing Fetterman, elected in 2022 with an everyman persona and irreverent wit, who was unafraid to challenge convention.

For some progressives, frustration with Fetterman began with his staunch support for Israel’s punishing war against Hamas in Gaza, an issue that divides Democrats.

It’s moved beyond that since Trump took office. Now, some are wondering why he’s — as they see it — kissing up to Trump, why he’s chastising fellow Democrats for their anti-Trump resistance and whether he’s even committed to their causes at all.

Most recently, they question his support for Trump’s bombing of Iran.

“It hurts,” said John Abbott, who attended Sunday’s event in suburban Harrisburg.

Speaking at the flagship “No Kings” rally in Philadelphia, Indivisible co-founder Leah Greenberg name-checked Fetterman.

“We’re looking to the leaders who will fight for us, because even today there are folks among the Democratic Party who think we should roll over and play dead,” Greenberg said. “Anyone seen John Fetterman here today?”

The crowd booed.

Why is Conor Lamb crisscrossing Pennsylvania again?

In Pittsburgh, progressives trying to land an in-person town hall with Fetterman or first-term Republican Sen. David McCormick noticed when the two senators advertised an event together at a downtown restaurant to celebrate the release of McCormick’s new book.

Progressive groups organized to protest it and — after it got moved to a private location with a private invite list — went ahead with their own town hall. They invited Lamb and a local Democratic state representative instead.

More invitations for Lamb started rolling in.

By his count, he’s now attended at least a dozen town halls and party events, easily clocking more than 2,000 miles to appear in small towns, small cities and suburbs, often in conservative areas.

“Showing up matters and it really does make a difference,” said Dana Kellerman, a Pittsburgh-based progressive organizer. “Is that going to matter to John Fetterman? I really don’t know. I don’t know what he’s thinking. I don’t know if he’s always been this person or if he’s changed in the last two years.”

Fetterman has brushed off criticism, saying he’s a committed Democrat, insisting he was elected to engage with Republicans and — perhaps hypocritically — questioning why Democrats would criticize fellow Democrats.

At times, Fetterman has criticized Trump, questioning the move to “punch our allies in the mouth” with tariffs or the need for cuts to social-safety net programs in the GOP’s legislation to extend 2017’s tax cuts. Fetterman’s office didn’t respond to an inquiry about Lamb.

Is Conor Lamb running for Senate?

For his part, Lamb — a former U.S. Marine and federal prosecutor — says he isn’t running for anything right now, but he’ll do whatever he can to “stop this slide that we’re on toward a less democratic country and try to create one in which there’s more opportunity for people.”

To some Democrats, he sounds like a candidate.

“That he’s doing these town halls is a good indication that he’ll be running for something, so it’s a good thing,” said Janet Bargh, who attended the event in suburban Harrisburg.

Aside from the town halls, he spoke at the Unite for Veterans event on the National Mall. He has also been active on social media, doing local radio appearances and appearing on MSNBC, where he recently criticized the June 14 military parade ordered up by Trump.

Not long ago, it was hard to envision Lamb losing a race, ever.

In 2018, he won a heavily Trump-friendly congressional district in southwestern Pennsylvania in a special election. It was the center of the political universe that spring, drawing campaign visits by Trump and then-presidential hopeful Joe Biden.

Suddenly, Lamb was ascendant. Then he ran for Senate and lost handily — by more than two-to-one — to Fetterman in 2022’s primary.

People often ask Lamb if he’s going to challenge Fetterman again. Lamb said he reminds them that Fetterman has three years left in his term and pivots the conversation to what Democrats need to do to win elections in 2025 and 2026.

Still, Lamb is unafraid to criticize Fetterman publicly. And, he said, he’s a magnet for Democrats to air their unhappiness with Fetterman. What he hears, over and over, is frustration that Fetterman spends too much time attacking fellow Democrats and not enough time challenging Trump.

“And that is, I think, what’s driving the frustration more than any one particular issue,” Lamb said.

At the town hall, Lamb wasn’t afraid to admit he’d lost to Fetterman. But he turned it into an attack line.

“When I watch the person who beat me give up on every important issue that he campaigned on … the more I reasoned that the point of all of this in the first place is advocacy for what’s right and wrong,” Lamb told the crowd. “And advocacy for not just a particular party to win, but for the type of country where it matters if, when you stand up, you tell the truth.”

The crowd cheered.
