"David McCormick seeks to unseat Democrat Bob Casey in Pennsylvania Senate race"

Republican David McCormick has announced his second bid for the U.S. Senate in Pennsylvania, aiming to challenge Democratic Senator Bob Casey. McCormick, a former hedge fund executive, criticized Casey for supporting President Joe Biden's policies and accused him of being a rubber stamp. The race between McCormick and Casey is expected to be closely watched and expensive, as Democrats face a challenging Senate map in 2024. McCormick lost in the Republican primary last year but has been heavily recruited by the party establishment to run again. Democrats have attacked McCormick's business record and his opposition to abortion rights. Casey, a long-serving Democrat in the Senate, is a key ally of labor unions and Biden.
