He was a long way from home, but in a sense returning to it.</p><p class="css-at9mc1 evys1bk0">“People living here have been receiving boil-water notices for two years now,” he said, using an expletive. “We should be banging the drums on this every day.”</p><p class="css-at9mc1 evys1bk0">Mr. Kennedy, 44, was retracing the steps of his grandfather, Robert F. Kennedy, the former attorney general and candidate for president, who toured the Delta in 1967 and encountered the kind of hunger and poverty more often associated with the developing world. “Those images Bobby took away of children with bloated stomachs and open sores had a huge impact on him,” said Evan Thomas, a biographer of both the elder Kennedy and his brother, President John F. Kennedy.</p><p class="css-at9mc1 evys1bk0">Mr. Kennedy nodded to the history. “I know a bit about my grandfather’s visit to the Delta back in the ’60s, and how it changed and outraged him to see this in the richest country in the world,” he said. “I’m proud that my family has spent a lot of their years in office advocating for these people.”</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="Dropzone-1"></div><div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-1"><div class="css-53u6y8"><p class="css-at9mc1 evys1bk0">Mr. Kennedy is on a mission to continue the legacy of an American political family that has in recent years lost some of its liberal luster.
