Mr. Trump hasnt (yet) offended blacks to the extent that hes offended other groups, but neither has he given many of them a reason to vote for him. Imagine if Mr. Trump took time to campaign in places like Jay Zs old neighborhood and talk to the residents about why so many lots are empty, why all those buildings are boarded up, why foreign nationals run so many of the small businesses, why the bodega charges so much for milk and eggs, why good schools and jobs are so scarce. He could explain why the Democratic politicians they continue to support have made so little progress in these communities. He could explain how he would do things differently. Mr. Trump, billionaire developer, would have both the knowledge and credibility to discuss these matters. And he would have an audience, likely a big one.
