WASHINGTON (AP) — For Donald Trump, the joy of the insult seems as compelling as the art of the deal.Whether his challengers are fellow presidential candidates, the press or others, they are, according to Trump: incompetent, weak, pathetic, disgusting, idiots or the like. He described Democratic presidential contender Martin O'Malley, for example, as acting "like a disgusting, little, weak, pathetic baby."So far in the rollicking 2016 presidential contest, the billionaire businessman is showing little willingness to dial down his because-I-said-so style to suit the conventions of political campaigns — where the voters are the ones making big hiring decisions.Trump is used to controlling his world like the boss he is.On Tuesday night, he dismissed a Latino reporter from his press conference for demanding to know how Trump intended to deport all 11 million people in the country illegally.
