Freshman Senator John Fetterman (D., Pa.) has spent recent months ruffling Democratic feathers in Washington for his outspoken pro-Israel views and decision to help Senate Republicans clear a filibuster for this month’s government-funding legislation, among other issues.

Fetterman’s 2022 primary rival, former Representative Conor Lamb (D., Pa.), has also spent recent weeks ragging on him, most recently for his government-funding vote and his joint scheduled appearance this weekend with the Keystone State’s freshman Republican senator, Dave McCormick. “Democrats know we have some issues, but he has a job to do,” Lamb told the Philadelphia Inquirer this week. “I know that trashing the Democratic Party gets him a lot of attention, but he wasn’t put in office to be a political commentator. He was sent to office to get results.”

Now Lamb is hosting a “people’s” town hall on Saturday, stoking speculation he may be putting out feelers for a prospective challenge against Fetterman in 2028.

When pressed by National Review on Wednesday whether he thinks Lamb will run against him in the future, he said: “I don’t comment on public citizens.” As a strategy, ignoring Lamb may not be unwise, considering that Fetterman defeated Lamb by more than 32 points in their 2022 primary.
