I personally do believe that indeed most of the polls constantly showing that the race is neck and neck is more a function of the mass media wanting to make more and more money by keeping the public nervous and uncertain than it is a function of actual data from scientifically carried out polls in different States.
It is not in the best financial interests of CNN, FOX, MSNBC, CBS, ABC, Newsmax or any other political news reporting source to make it appear as if one candidate or another has a significant lead. Put another way, I do believe corporate media in America is lying to us, - but for financial reasons, not ideological reasons.
We are being lied to not because any corporate executives necessarily care who wins the election. Generating more money is all they are interested in. It has obviously been like that for at least the past 3 presidential elections.
Trump's ascension is even more dangerous to ignore.
