WASHINGTON (AP) — At the top of his first speech as her running mate, Minnesota Gov. Tim Walz turned to Vice President Kamala Harris and declared, “Thank you for bringing back the joy.” The next day, Harris took the theme a step further, branding the Democratic ticket “joyful warriors.” Contrast that with former President Donald Trump, who opened a news conference at his Mar-a-Lago club in Florida later in the week saying, “We have a lot of bad things coming up.” Democrats are playing up their sunnier outlook. But the Trump campaign argues their candidate is reflecting the country’s more accurate, dour mood.
