Donald Trump, the supposed voice for the forgotten man who descended from his gold-encrusted New York City shrine to speak to the American voter who had been left behind, bullied a union boss by name on Wednesday night.

“What do I have to say about a person with their finger on the nuclear button going after someone who has a flip phone,” RoseAnn DeMoro, executive director of National Nurses United, laughingly said in a phone interview. “It’s just too crazy.
