In a seering, and humourous, column, Republican George Will blasts Trump's ignorance. Here are the choice lines:
It is not merely the result of intellectual sloth but of an untrained mind bereft of information and married to stratospheric self-confidence.
As this column has said before, the problem isn’t that he does not know this or that, or that he does not know that he does not know this or that. Rather, the dangerous thing is that he does not know what it is to know something.
His fathomless lack of interest in America’s path to the present and his limitless gullibility leave him susceptible to being blown about by gusts of factoids that cling like lint to a disorderly mind.
I think "gusts of factoids that cling like lint to a disorderly mind" should go down in history as one of the great lines of the Republic.
