The field of politics, despite many cynics, is a PROFESSION, and requires a lot of training and expertise to do it well.
That is why people who go into politics run for local office and state office usually before running for national office, such as the Senate and House of Representatives.
That is why ALL Presidential winners in our history, except for three generals–Zachary Taylor, Ulysses Grant, and Dwight D. Eisenhower–have had some kind of political experience before becoming President.
Only two people have ever been nominated for the Presidency WITHOUT any political or military experience–Wendell Willkie in 1940 by the Republicans, and Ross Perot, who ran as an Independent and Reform Party candidate in 1992 and 1996.
The thought of Herman Cain running for the Presidency without any knowledge or expertise in any field of government policy turned out to be a total disaster, beyond his own moral and ethical issues. It is obvious that Herman Cain undermined the respect of the Presidential office by having the gall to run, knowing full well that he was not qualified by any measurement!
Cain took advantage of his race to enter the race, knowing no one would dare challenge it because of his race. But all he did was exploit the publicity that one gains running for the Presidency to sell books, promote more lucrative, highly paid speeches, and to gain the opportunity for a likely television show, because now he is a celebrity, who loves the spotlight and the ability to profit from it by his associations with the political class that he knows nothing about!
This disaster of Herman Cain is good enough reason to say that never again should an arrogant businessman, including Donald Trump, think he or she is qualified to hold our highest office! If one wishes to strive for such, get serious and get experience in politics and political office first before lessening the dignity of the Presidency for one’s own selfish gains!
