Employees, executives, aides and others who’ve known Trump well say he’s not a book-reader so much as a room-reader, “sucking in information that he finds valuable,” grabbing “nuggets” that he thinks can help him get what he covets, which is some slurry of wealth, attention, respect and power. “A creature of feel,” the late strategist Pat Caddell described him to me in the summer of 2018, “a visceral stimulus creature”—who could repackage what he took in and sell it back to the hoi polloi. He talked to Pat Caddell about what he was picking up on the trail. “He would put forth his position or his feelings, and he would judge the level of the response to it, and that helped him organize, I suppose to whatever degree it was organized, his views about issues,” Caddell told me in 2018. “Things he said that didn’t go over disappeared. Things that did stayed.”
