How much more ridiculous is the Republican presidential campaign going to get?

“I predicted Osama bin Laden,” Mr. Trump declared in Knoxville, adding, “In my book, I predicted terrorism. Because I can feel it, like I feel a good location, O.K.?”

“In real estate — my father always used to tell people, ‘You know, he may be my son, but everything he touches turns to gold,’” Mr. Trump said. His father helped him begin his real estate career with a loan. “When my father said that, that was a great compliment because he was a tough cookie. He said, ‘He has an instinct for location.’ You have an instinct about things. I really believe I have an instinct for this kind of thing.”
