WASHINGTON (AP) — President Joe Biden is going to Pennsylvania again. On Friday, he’s championing steep increases in federal public works spending and detailing how promoting green energy can bolster U.S. manufacturing. In Philadelphia, he will announce that the city will be one of the regional hubs selected to produce and deliver hydrogen fuel that can run factories, ports and other facilities. But much has changed since Biden made his last trip to a familiar place to hit on a familiar theme. The war between Israel and Hamas has scrambled geopolitics and potentially reshuffled the 2024 presidential race. So there’s a question whether a familiar economic message in a place the president visits frequently will really get noticed.
