Biden makes rare dip into battleground state fray with a visit to Pennsylvania and Wisconsin

President Joe Biden is making a rare jump into the 2024 battleground political fray since ending his reelection bid. He'll campaign on Tuesday in Pennsylvania for a close ally and visit Wisconsin to spotlight a signature legislative achievement. But as Biden makes a quick swing through the key states, two Democratic senators locked in competitive reelection battles are taking markedly different approaches to the outgoing president. Biden will be fully embraced by Sen. Bob Casey when he participates in an evening campaign fundraiser in Philadelphia with Pennsylvania's senior senator. But in Milwaukee, where Biden is spotlighting his administration’s efforts to replace the nation’s toxic lead pipes, incumbent Democratic Sen. Tammy Baldwin will be conspicuously absent.
