"Former Bridgewater CEO Dave McCormick enters Pennsylvania Senate race with potential big money backing"

Businessman Dave McCormick has announced his candidacy for the Pennsylvania Senate race, setting up a potential battle with Democratic incumbent Sen. Bob Casey. McCormick, who narrowly lost a previous Senate bid, has garnered broad support within the GOP and is expected to secure the party's primary nomination. Pennsylvania is a critical swing state, and McCormick's entrance into the race is seen as a significant win for Republican Party leaders. While Casey has a strong track record in previous elections, McCormick's ability to unite both grassroots and establishment support has generated excitement among Republicans.
