If Donald J. Trump wins reelection today, it will make David’s defeat of Goliath look like a foregone conclusion. “Goliath got his ass kicked,” said the Philistine, “big deal.” Never in American history has a presidential candidate faced such committed, sustained, and malicious opposition from such formidable opponents. One could credibly argue that a Trump victory would be nothing short of miraculous considering the headwinds against which our 45th President has struggled. Buster Douglas defeating Mike Tyson was ho-hum compared to Trump’s challenges. Harry Truman’s defeat of Thomas Dewey was a walk in the park.
