Vice President Kamala Harris and her new running mate, Minnesota Gov. Tim Walz, are campaigning in Arizona, a critical battleground state, as they prepare for the presidential race against Donald Trump. This rally marks Harris's first major event since taking the Democratic nomination from President Biden, who recently stepped aside. Polls indicate a competitive race, with Harris showing a narrow lead over Trump, a shift from earlier months when Biden was trailing. The campaign is focusing on key issues such as reproductive rights and border security while targeting diverse voter demographics, including young and Latino voters. Additionally, Harris's decision to choose Walz over Arizona Senator Mark Kelly has sparked debate among local Democrats, but enthusiasm remains high for the ticket. Trump is concurrently holding a rally in Montana, underscoring the high stakes for both parties in upcoming elections.
