Donald Trump was raised in the chapel of positive thoughts. While he was growing up, Trump’s family attended the Manhattan church of Norman Vincent Peale, the evangelist who preached self-realization and wrote the 1952 best-selling book The Power of Positive Thinking. Trump rarely talks about losing anything. That’s why aides were puzzled late last week when the President, during a blitz of rallies in battleground states, repeatedly brought up the possibility of losing to former Vice President Joe Biden.
