Democrats in Pennsylvania Urge Biden to Branch Out Beyond Philadelphia

President Biden loves Philadelphia. And he loves campaigning there, too.

No part of the country has seen more visits from Mr. Biden so far this year, or throughout his presidency.

Mr. Biden will need to reunite that multiracial coalition of voters — which polling shows is in danger of fracturing — in 2024.

Mr. Lamb acknowledged that all candidates have time constraints, especially the president of the United States. But he urged Mr. Biden
