Dave McCormick, the Republican nominee for U.S. Senate in Pennsylvania, faced backlash after mistakenly referencing a shooting incident in Philadelphia, Mississippi, as occurring in Philadelphia, Pennsylvania. His post on social media claimed that MS-13 gang members were terrorizing Philadelphians due to the 'open border policies' of his opponent, incumbent Senator Bob Casey, and Vice President Kamala Harris. The post was quickly deleted after the error was pointed out, leading to mockery from Casey's campaign, which highlighted McCormick's part-time residency in Connecticut. McCormick acknowledged the mistake but shifted focus back to criticizing Casey. This incident adds to ongoing scrutiny regarding McCormick's ties to Connecticut and his claim as a long-time Pennsylvanian amid accusations of being a 'carpetbagger'. His campaign is in a tight race against Casey, who currently leads in the polls.
