Republican David McCormick claims victory in Pennsylvania's U.S. Senate race against incumbent Democrat Bob Casey, with a lead of less than 31,000 votes, according to multiple sources. Despite McCormick's declaration, the race remains too close to call, with a margin small enough to potentially trigger an automatic recount under state law, as McCormick holds 48.9% to Casey's 48.5% with over 97% of votes counted. Both campaigns express confidence, citing uncounted ballots in their respective strongholds, with McCormick's team focused on conservative areas and Casey's team on Democrat-heavy regions like Philadelphia. This race is pivotal for the Republican party, which has already secured at least 53 seats in the Senate, potentially expanding their majority. As one of the most expensive Senate races in 2024, both candidates have centered their campaigns on issues such as inflation, immigration, and tax policies. Given the narrow margin, the election outcome might extend into weeks due to provisional ballots and the recount process.
