At a campaign rally in Iowa Tuesday, Republican presidential contender Donald Trump reacted to his falling poll numbers in the state.

"What the hell are you people doing to me?" Trump asked the crowd. "Iowa, will you get your numbers up, please? Will you get these numbers up? I promise you: I will do such a good job."

On "Special Report" tonight, Charles Krauthammer said that it was very unusual to see Trump openly tell the audience that the election is all about him, not them.

He pointed out that Trump defines everything and everybody in terms of winning or losing.

"When he loses, can he handle it?" Krauthammer wondered. "If it's anything like what he did yesterday, this could be an inflection point."
