Vice President Kamala Harris and former President Donald Trump both took their 2024 campaigns to Pennsylvania Monday night to paint their opponent as a danger to America’s future.

Harris, whose emphasis on “joy” led to a surge in national and battleground polling over the summer, has stalled somewhat in the final stretch of the election. Her campaign rally Monday night in Erie, Pennsylvania, marked the first stop of four across the Midwestern “blue wall” this week. Trump held a campaign rally in Erie in late September.
