Tonight, Vice President Kamala Harris and former President Donald Trump will engage in a pivotal presidential debate at Philadelphia's National Constitution Center. The debate will last 90 minutes, featuring strict rules including muted microphones and no audience, with critical questions surrounding tax cuts, the war in Ukraine, and U.S.-Israel relations. Harris, viewed as an underdog since taking over from Biden, will rely on her prosecutorial skills to challenge Trump, who has a history of dominating debate stages. Both candidates aim to sway undecided voters in a tightly contested race, with Harris's campaign emphasizing strong leadership in contrast to Trump's controversial rhetoric. Additionally, a geomagnetic storm may provide a backdrop of northern lights visible across parts of the U.S. on debate night. As voters look ahead, the debate could significantly influence public perception and campaign momentum.
