Republican vice presidential candidate JD Vance is ramping up his campaign efforts in key states, including an upcoming rally in Newtown, Pennsylvania, scheduled for September 28. Vance, a U.S. senator from Ohio and former critic of Trump, has been focusing on Pennsylvania, a critical swing state. Recently, he held campaign events in Arizona, including rallies at Generation Church in Mesa and a prestigious event at the Arizona Biltmore, aimed at energizing Trump's base. His campaign strategy includes engaging with conservative activists and leveraging his military background to appeal to voters. Despite some past controversies, Vance's campaign is gaining momentum as he prepares for a debate against Kamala Harris’ running mate next month. The Trump campaign remains tight-lipped about specific rally attendance details, but interest among supporters appears to be high.
