DES MOINES, IOWA (The Borowitz Report)—Businessman Donald Trump's failure to insult fellow G.O.P. hopeful John Kasich a full twenty-four hours after the Ohio governor entered the 2016 Presidential race has sent Trump's poll numbers plummeting, as many supporters expressed a sudden loss of confidence in the real-estate mogul.

Trump's Kasich gaffe occurred at a campaign rally in Des Moines on Wednesday, when the former reality-show star admitted that he did not yet know enough about the Ohio governor to properly insult him.

"I could get up here and call Kasich a loser, because my gut tells me that's what he is, but you've come to expect something more special out of me," Trump said. "If you bear with me, I promise you that I'll come up with a world-class insult that we can all be proud of."

The audience reacted with stunned silence, leading some observers to question whether Trump's failure to insult Kasich would turn from a mere gaffe into a full-blown scandal.

Carol Foyler, a Trump supporter who attended the Des Moines event, said that she still liked Trump because of the insults he had delivered in the past, but she acknowledged that her belief in him had been shaken.

"When you're in the White House and that phone rings, you've got to be ready to insult someone right away," she said.
