The battle for the Upper Midwest began in earnest on Wednesday, with the Harris and Trump campaigns making dueling appearances in the same cities. Vice President Kamala Harris and her new running mate, Gov. Tim Walz of Minnesota, wrapped up their day with a rally in Michigan, where Senator JD Vance of Ohio began his.
Another large and energetic crowd gathered to meet Ms. Harris and Mr. Walz at an airport hangar in Detroit, just hours after they spoke at a packed rally in Eau Claire, Wis. Raucous supporters spilled onto the Detroit tarmac and cheered Ms. Harris’s arrival on Air Force Two. Her campaign said 15,000 people attended the event, which appeared to make it Ms. Harris’s largest yet.
