After every loutish performance, political analysts pronounce Donald Trump’s presidential bid finally dead. Surely he cannot recover, they insist, from libeling all Mexicans, denigrating the military heroism of Sen. John McCain, or making crude insinuations about the popular Fox News host Megyn Kelly. But somehow, his predicted demise fails to materialize. Instead, new polls appear showing the billionaire property mogul to be more popular than ever. By most measures, Trump now leads the Republican field by a substantial margin.
