“Folks, I’m running for reelection,” Casey, 62, said in an announcement posted on Twitter. “There’s still more work to do to cut through the gridlock, stand up to powerful special interests and make the lives of hardworking Pennsylvanians easier. The map is back, and I’m not done yet.”
Pennsylvania is one of several Senate battlegrounds where the party will be pressed to defend its slim majority. In 2022, the open seat Senate race in the Keystone State between Democrat John Fetterman, the eventual winner, and Republican Mehmet Oz was among the most expensive and competitive of the cycle.
Casey is seeking his fourth term representing Pennsylvania in the Senate. The veteran Democrat had been noncommittal on his reelection plans up to this point, and in February he announced that he had undergone surgery for prostate cancer which “should not require further treatment,” according to his office.
According to his latest FEC filings – which are set to be updated later this week – Casey had a little over $3 million in cash on hand stockpiled as of the end of 2022. Those funds and more will be critical in the upcoming contest, as Casey’s colleague, Fetterman, raised more than $76 million during his competitive 2022 race.
Potential Republican challengers include David McCormick, a wealthy businessman who unsuccessfully ran against Oz in the state’s 2022 GOP Senate primary and who could pour millions from his personal fortune into another bid.
McCormick has publicly expressed interest in the race, releasing a book and touring.
“I’m thinking about it, obviously,” McCormick told CNN about a potential Senate run.
And Doug Mastriano, the unsuccessful far-right nominee for governor in 2022, has also teased the possibility of running for Senate in 2024.
“What do you do with a movement of 2.2 million?” Mastriano told Politico. “We’re keeping it alive.”
Casey could stand to benefit from a competitive GOP primary with echoes of 2022, when a drawn out, bitter contest between McCormick and Oz helped Fetterman strengthen his position heading into the fall campaign.
