Not bullshit. The pollsters biased the sampling to OVERWEIGHT reliable Dems and Reps. And IGNORED the larger part of the voting population.
all pollsters or t hose doing the analysis of polls?
Most all of the important ones. Like in the states that seemed locked for Hillary. Polling is largely an exercise based on HISTORY. and they ALL got LEANED towards past performance. They were completely USELESS.
In fact, and I've looked into this, there is a whole NEW generation of polling techniques. Ones that do NOT rely on phone dialing, which is insane in this day and age. Ones that PRE-VET the voting tendencies of ACTUAL people. And THESE folks are compiling MILLIONS of potential people to be polled with extensive "vetting" into their actual voting patterns and preferences. It's a REVOLUTION in polling technique to overcome the trend towards voter independence from being captive to a particular party..
Part of reading polls ----- in fact really most of it ---- is not in snapshots of what respondents said on a particular day but rather
trends. My own state was showing Clinton ahead by comfortable margins... then by slim margins.. then by razor thin, then teetering to red. By election day it was clear where the trend was pointing.
I wasn't following the Ohios and Pennsylvanias and Wisconins as closely but I suspect they too showed the same
trends. That's why you take polls over and over ---- to get a sense of
movement. A still picture, even one taken the day before the election, means nothing without its context.
It's just like looking at baseball standings on a random date and going "the New York Mets have more wins this season, therefore they must be the best team around, I'll bet on them to win" while oblivious to the fact that they've lost 9 of their last 10
recently.
Bottom line --- I don't think the polls were as "off" as is popularly mythed at all. They were indeed showing these trends, especially after the Comey letter, which was very late in the game and therefore didn't allow a whole lot of time to SEE a trend, but it was there for those with the skill to perceive it.
