Washington Donald Trump on Thursday told Iowa's voters that those who support Ben Carson are "stupid" to believe the "crap" that is his life story, part of a dizzying rhetorical romp in which Trump offered his most animated attack yet on his closest competitor.
At one point, Trump walked away from the podium and flipped his belt buckle up and down to ridicule what Carson has described as a key event in his life: that Carson, as a boy, once tried but failed to stab someone only to have the knife broken by a belt buckle.
Moments later, Trump told the crowd in Fort Dodge that he could not possibly understand why anyone supports Carson, who is essentially tied with Trump for support in the first-voting state.
