In a country with more than 300 million people, it is remarkable how obsessed the media have become with just one -- Donald Trump. What is even more remarkable is that, after six years of repeated disasters, both domestically and internationally, under a glib egomaniac in the White House, so many potential voters are turning to another glib egomaniac to be his successor. No doubt much of the stampede of Republican voters toward Mr. Trump is based on their disgust with the Republican establishment. The fact that the next two biggest vote-getters in the polls are also complete outsiders -- Dr. Ben Carson and Ms. Carly Fiorina -- reinforces the idea that this is a protest.
