Republican David McCormick has defeated three-term Democratic incumbent Bob Casey in Pennsylvania's Senate race. This victory solidifies the GOP's Senate majority at 53 seats and represents a significant shift in political dynamics in Pennsylvania. McCormick focused his campaign on inflation, immigration, and dissatisfaction with Biden Administration policies, leveraging deep financial backing from his hedge-fund connections. Despite leading by a narrow margin of around 31,000 votes, Casey's campaign has not conceded due to over 90,000 votes still being counted, which may trigger a recount. This race underscores the evolving political landscape in Pennsylvania.
