Donald Trump is big on denial.
Didn't win the popular vote? Deny it and invent a story about massive voter fraud to back up your denial. Not getting anything done? Deny it and make an outlandish claim that you have done more in six months than any other president in modern time. Problems accepting the overwhelming scientific evidence on global warming? Deny science and claim thay you know better. Failing to attract a large crowd in your "rallies"? Deny it and inflate the number of participants far beyond credibility. Accused of crimes? Deny everything. Said stupid things? Deny it, even in the face of recordings. Problems facing reality? Deny it and substitute your own fantasy world where you are smart and successful instead of a failing, stupid loser.
Denial doesn't work. At least, not for long.
