Trump, and his inner circle jerk, have totally misread the breadth and depth of their support in the country. It is a natural shortcoming of cave dwellers, breathing their own Methane for too long. When all of your "nutrition" comes from licking guano off the grotto walls, it leads to a mineral deficiency resulting in severe political myopia. The reason the Republican Party isn't willing to describe any future for Americans to believe in is because, unlike the Democrats, they have no vision that extends all the way to the horizon. All they can see is the end of thier own nose. That's the biggest reason for Congressional paralysis. They can't get anything done because they don't know what to do.
As with every other presidential election in the last 30+ years, the profit driven corporate main stream media will keep selling the public the idea that this race is close . . . even though it isn't. Political campaigns pump billions into corporate MSM coffers in presidential election years, because a close race = more $ to the parties = more media advertising $.
The MSM isn't "left wing". The MSM is corporate, and the only ideology it serves is the bottom line. It has no obligation to tell the truth to the American public. It's only obligation is fiduciary - i.e. to its shareholders. So the news, as in real news, is nothing but a loss leader in the broadcast industry, including internet advertising. They make more money manipulating public perception into believing the race is closer than it really is. What it really is is ... Trump loses.
The polls might always be closer - within the infamous "margin of error" - but the way the polling questions are structured, sequenced, the demographics of those polled, and the final "interpretation" of those results, will always make for the appearance of a closer race than reality.
And the reality is - Trump loses .... bigly!
