Since then, the targets of Trump's insults expanded to include women, African-American protesters, family members of rivals, etc.

According to a list compiled by The New York Times, Trump had insulted on Twitter 210 individuals, places and things since declaring his presidential candidacy last June.

The Times list did not include targets of Trump's insults broadcasted on cable.

Despite the urgency to unite the divided GOP, Trump indicated in his recent interview with the New York Times that he had a "mandate" from his supporters to continue his candidacy as a "fiery populist outsider."

"You win the pennant and now you're in the World Series - you gonna change?" said Trump to The Times. "People like the way I'm doing."
