"This book is my answer to Trump-the-question. Because Mr. Trump stirs up so much controversy, I knew that only hard evidence could keep me from being tossed about in his wake. So I have assembled a great quantity of data here, looking exhaustively at Trump's speeches, his press conferences, his debates, and his incessant tweets. But these data mean little by themselves. It is only when one compares them to what the press has written that one begins to get the full measure of the man, a project also advanced by looking at what everyday citizens have said when writing letters to the editors or when responding to nationwide surveys. Donald Trump, I came to believe, can only be understood by triangulation."--
