As vote counting continues in Pennsylvania, three crucial U.S. House races remain uncalled, with Republican candidates holding tight leads. Incumbent Democrats, including Susan Wild and Matt Cartwright, have conceded to their Republican challengers, Ryan Mackenzie and Rob Bresnahan, respectively. The outcomes could shift the balance of power in the House, enabling a potential full Republican majority alongside President-elect Trump. This cycle marks significant election dynamics in a state that has leaned Democratic in recent years, reflecting growing partisan divides among voters in key districts.
