Vice President Kamala Harris is gearing up for her first campaign rally in Philadelphia on August 6, alongside her yet-to-be-announced running mate. Following President Biden's withdrawal from the presidential race, Harris has emerged as the presumptive Democratic nominee and plans to visit seven swing states, including Detroit and Las Vegas, in a bid to strengthen her campaign. Speculation surrounds possible running mates, with Pennsylvania Governor Josh Shapiro, Arizona Senator Mark Kelly, and Kentucky Governor Andy Beshear among the top contenders, although Harris has not yet made a decision. Reports indicate that Harris's campaign is vetting a dozen potential candidates, but the final choice remains uncertain as she prepares for upcoming interviews. The rally in Philadelphia will mark a significant milestone as the duo embarks on their campaign tour, highlighting the importance of key battleground states for the upcoming election. Harris's team emphasizes the broader electoral strategy, suggesting an expanded map since Biden's exit, despite the ongoing speculation over her running mate selection.
