LINDA KISSEL was afraid to go to the stadium. On September 21st the home of the Arizona Cardinals, an American football team, was transformed into a memorial for Charlie Kirk, a conservative provocateur who was assassinated nearly two weeks ago at a college campus in Utah. Tens of thousands of mourners wearing MAGA hats, cowboy couture and red, white and blue streamed into the venue. The event was equal parts memorial, megachurch service  and political rally. Yet Ms Kissel was uneasy. She worried that the stadium would become a target for yet another attack. “I feel like we’re so divided,” she says. “I want us to be the re-United States of America.”
