As Trump's World Turns: The POLLS?

Marquee Scroll>57 Percent Want A New Leader In The White House

Trump at one time-loved to quote "the polls" or "the ratings".  We haven't heard those words form the nation's 45th President in many months. Every wonder why?

Maybe a recent poll leads us to an answer.

In May 2018 the FiveThirtyEight Blog( Nate Silver) published what follows.

Which Pollsters To Trust In 2018

Negative plus-minus scores are good and indicate that the pollster has had less error than other pollsters in similar types of races.
The “average error” is the difference between the polled result and the actual result for the margin separating the top two finishers in the race.
“Bias” is a pollster’s average statistical bias toward Democratic or Republican candidates. 
The best of these pollsters over this period has been Monmouth University, which has an Advanced Plus-Minus score of -1.5. That’s not a huge surprise — Monmouth was already one of our highest-rated pollsters. After that, the list is somewhat eclectic, including traditional, live-caller pollsters such as Siena College and Marist College, as well as automated pollsters such as Emerson College and Landmark Communications. Polling institutes run by colleges and universities are somewhat overrepresented among the high performers on the list and have generally become a crucial source of polling as other high-quality pollsters have fallen by the wayside.
Data, when applied without bias, is irrefutable.  Let's see how Nate Silver's data shows in 2020.
