Democratic Senator Bob Casey conceded his Pennsylvania Senate race to Republican David McCormick, who won by a narrow margin of 16,000 votes. The close election triggered an automatic recount, and McCormick's victory solidifies the GOP's 53-seat majority in the Senate. Casey praised the electoral process and expressed gratitude for the efforts made to ensure all votes were counted. McCormick, in his victory statement, expressed honor in representing Pennsylvania and credited Casey for his dedicated public service. The outcome reflects a shift in political dynamics as Republicans are set to control both Congress and the White House.
