Decision 2024: Pennsylvania’s 2024 U.S. Senate race

After losing a close GOP primary battle for Pennsylvania’s other U.S. Senate seat in 2022 to celebrity physician Mehmet Oz, McCormick secured the Republican nomination in 2024 with relative ease, lining up a general election matchup with Casey, who has served in the Senate since 2007. Nonpartisan election analysts believe the seat will be competitive this fall; the Cook Political Report updated the race to a “Toss Up” in October, while Sabato’s Crystal Ball, a project of the University of Virginia’s Center for Politics, rated it “Lean D,” and Inside Elections has the seat rated “Tilt Democratic” for 2024.

City & State has your guide to the campaign, with candidate endorsements and more.

U.S. Sen. Bob Casey

Casey has served in the U.S. Senate since winning his first general election in 2006 and subsequently being reelected in 2012 and 2018. Prior to his time in the Senate, he held statewide office, serving as Pennsylvania auditor general from 1997 to 2005 and then as Pennsylvania treasurer from 2005 to 2007. 

Throughout his time in the Senate, Casey’s work has focused heavily on policies designed to help children, disabled individuals and older adults, with Casey chairing the U.S. Senate Committee on Aging. Over the last year, Casey has also focused on “greedflation” – the purported use of inflation by companies to raise prices – and “shrinkflation” – the sale of products in smaller sizes and quantities at the same price. He has introduced legislation at the federal level, dubbed the Shrinkflation Prevention Act, that would authorize the Federal Trade Commission to crack down on the practice. 

During his time in the Senate and on the campaign trail, Casey has made protecting Social Security and Medicare another major priority. In an interview with City & State earlier this year, Casey called Medicare a vital program. “Medicare is so vital for the lives of tens of millions of Americans – and yet, it’s the official position of the Republican Party to turn Medicare into a voucher program,” Casey said. “They’ve proposed it year after year. It’s an obnoxious idea and we have to stop it.”

Dave McCormick

McCormick is the former CEO of asset management firm Bridgewater Associates. Prior to his time at Bridgewater, he had a stint in government as Under Secretary of Commerce for Industry and Security in then-President George W. Bush’s administration and later as United States Deputy National Security Adviser for International Economic Affairs. He’s a U.S. Army veteran who graduated from West Point and was deployed to the Middle East during the First Gulf War. 

McCormick has sought to draw a stark contrast between himself and Casey throughout the campaign, including making promises to support policies that strengthen security at the U.S.-Mexico border and combat violent crime in the United States. He has also said America needs to strengthen its standing both domestically and on the world stage, telling City & State last year: “America needs to go to the gym and do the basic things we need to regain our strength, regain our internal strength,” he said.

McCormick spoke at this year’s Republican National Convention, where he said this year’s U.S. Senate election “is the most important election of our lifetimes,” adding: “My friends, the choice this November is clear. It’s a choice between strength and weakness, a choice between America’s greatness or its sad, disgraceful decline.”
