American's tend to root for the underdog. It is almost our nature. Perhaps it has something to do with the American Revolution. In the war for our freedom, you couldn't find a greater underdog story than the Continental Army versus England.
Donald Trump is not someone who fits the profile of an underdog. To begin with he is a billionaire. His Apprentice show and the entire "Trump Tower" brand certainly do not fit the image of an underdog. He is always talking about "winning." Trump is more likely to be characterized as a bully than an as an underdog. And yet ...in many respects Trump is the greatest underdog story there ever was.
Before I even start to list why Trump is an underdog, the fact that the first political race he ever entered for was PRESIDENT automatically makes him an underdog out of the gate.
In his Primary race nobody gave him a chance. He was mocked and laughed at by even those in his own party. People not only mocked Trump, they thought there was something wrong with anyone who thought he would win. The pollsters have never given Trump a chance - not in 2016 or 2020.
For 4+ years Trump has faced the hostilities of Nancy Pelosi's House, Adam Shift's National Intelligence Committee, Jerry Nadler's Judiciary Committee, the entire mainstream news media, Hollywood, most every TV show, the NFL, heads of Twitter, Amazon, Facebook, the NY Times, Washington Post and every other major Newspaper, not mention Democrat governors and mayors in NY and across the USA.
And let's not forget the CIA, Comey's FBI, the Mueller investigators and the Washington D.C. establishment who have been out destroy Trump.
Trump has even had to fight against China and a pandemic.
Ironically, it took the prospects of Trump losing the Presidential election for folks who never thought of him as an underdog to finally start to see what Trump is up against.
When you consider what Trump has been up against in American Presidential politics, Trump is a HUGE underdog story! He is even an underdog for being an underdog.
America loves an underdog!
