Vice President Kamala Harris and Minnesota Governor Tim Walz are launching their campaign in Eau Claire, Wisconsin, marking the first full day of their joint effort. They will hold a rally at the Eau Claire Event District, while Republican nominee Sen. J.D. Vance will host a separate event nearby. Both candidates are focusing on battleground states, with Harris and Walz scheduled to continue their campaign in Michigan, Georgia, Arizona, and Nevada. A recent poll indicates that while Walz remains largely unknown to the public, Vance is experiencing increasing unfavorable ratings. The Democratic ticket will be officially nominated at the Democratic National Convention in Chicago starting August 19. Both campaigns had to cancel events in North Carolina due to Tropical Storm Debby.
