Americans may describe the billionaire businessman’s behavior in many ways, but psychologists and experts told USA TODAY that textbook bullying shouldn’t be one of them. The greater challenge, the bullying experts say, is explaining the reasons for Trump’s popularity in a culture that is supposed to frown on naked aggression.

“Bullying is the repeated, intentional harm of another person who has less power than you do,” said Dewey Cornell, a forensic psychologist and bullying expert at the University of Virginia.

“If it’s him and Rosie O’Donnell going at each other, they may have comparable power,” he said.

Patti McDougall, associate professor of psychology at the University of Saskatchewan echoed that, saying ”bullying does not happen when you’ve got two equals in a fight.”
