The Economist summarizes the worst of Trump (so far):
Because each additional Trumpism seems a bit less shocking than the one before, there is a danger of becoming desensitised to his outbursts. To recap, he has referred to Mexicans crossing the border as rapists; called enthusiastically for the use of torture; hinted that Antonin Scalia, a Supreme Court justice, was murdered; proposed banning all Muslims from visiting America; advocated killing the families of terrorists; and repeated, approvingly, a damaging fiction that a century ago American soldiers in the Philippines dipped their ammunition in pigs’ blood before executing Muslim rebels. At a recent rally he said he would like to punch a protester in the face. This is by no means an exhaustive list.
