Biden Takes On Campaign Duty in Pennsylvania, Celebrating Unions

President Biden and Jill Biden, the first lady, joined the pitched electoral struggle over Pennsylvania on Tuesday, fanning out with three appearances across the Philadelphia area intended to aid Vice President Kamala Harris in what may be the most consequential swing state.

While his wife helped staff a phone bank across town, Mr. Biden joined a dinner held by the Philadelphia Democratic City Committee at the local sheet metal workers’ union hall, where he revved up attendees with a punchy speech and unleashed a long list of attacks against former President Donald J. Trump.

“He has the same ideas on race as the 1930s. Trump’s ideas on the economy are from the ’20s. Trump’s ideas on women are from the ’50s,” he said. “Folks, this is 2024. We can’t go back.”

But as often as Mr. Biden sought to contrast his record with Mr. Trump’s, he carefully tacked back several times to express support for Ms. Harris. He compared her to himself in growing out of his role as former President Barack Obama’s running mate, seeking to support her without defining her in his own unpopular image.

“I was loyal to Barack Obama, but I cut my own path as president,” he said. “That’s what Kamala is going to do. She’s been loyal so far, but she’s going to cut her own path.”

Mr. Biden’s visit was a reminder that just three weeks before the election, even when the presidential candidates are not in Pennsylvania, they are well aware of the need to maintain a presence in the state. With 19 electoral votes, it is the largest of the battleground prizes, and both campaigns would face narrow paths to victory without it.
