Again note that they are using registered voters not likely voters. At this late date if you are not polling likely voters your poll is going to be inaccurate.
That's the point of selective push-polling - to demoralize the voters for the opposition.
All polling this cycle is completely worthless except for observing trends within the same poll/methodology.
The Special Sauce all pollsters use to normalize and extrapolate for age, gender, race etc. have no relevance with so many Democrat and Republican defections. Each candidate is likely to suffer a 20-30% loss of their own party, and conversely benefit from the same.
ALL polls this cycle, no matter have bad or favorable, are sh!t.
Registered voter polls I dismiss out of hand. They’re posted for the purpose of make it look like Hillary is far ahead. She’s not.
