PLEASANT HILL, IA—Shaking his head as he watched coverage of the city’s flooded subway system during a campaign stop, presidential candidate Bill de Blasio was overheard remarking Tuesday that New York appeared to be a complete and total disaster. “I can’t believe how miserable and hopeless that place looks,” de Blasio said as he visited the Pleasant Hill Diner in Iowa, observing that if he were elected president, then perhaps New Yorkers wouldn’t have to worry about such terrible things happening anymore. “How can people there stand it? I know I don’t want to live in a place like that. Somebody really ought to do something.” Before his aides ushered him to his next campaign event, De Blasio took one last look at the television and muttered that he was glad he didn’t have to deal with any of that mess.
