@Leth...
I understand polling juts fine, I just suspect that you are a mind-number liberal in denial of the attempted fixing that has taken place in the media.
I understand this:
1. The media long ago stopped being about "reporting the news" and, especially this elections cycle, and OPENLY ADMITTING IT, they have been trying to persuade the voters opinions.
2. POLLS therefore have often times become less about "reporting the opinion of..." and have as much become about "persuading the opinion of..."
3. Because Americans -- yourself, for example -- are probably more interested in "being right" than they are about "getting it right"
4. Therefore if Joe-Moron Average American sees an article that says "Polls put Killary up by XX points", the media *believes* that Average "undecided" Joe-Moron American will say, "Wellllll shi-i-i-i-i-t....I's better gets my vote in fer Killary too...because I'd rather be right with the crowd, than get it right" and the media thinks therefore they can influence the election VIA THE REPORTING OF POLLS THAT THEY CONTROL....
5. Therefore, in order to CREATE POLLS THAT INFLUENCE the election, rather than report actual unbiased feelings, they create polls that are an attempt to model what they believe is going to be the turnout.
So....while they may sample 100 Republipukes and 100 Demoncrats and 50 "Independants", they will not report the results precisely as they came in. Instead, they will examine their "models" and say "likely turnout is 70 Republipukes, 85 Demoncras and 34 Independents" and therefroe they WEIGHT THE REPORTED RESULTS based upon what their model predict the turnout to be.
Except their predicted turnout is complete and utter bullshti.
We KNOW that most of the polls have been MASSIVELY OVERSAMPLING THE DEMONCRATS.....so in thei model...they think there will be a much higher turnout of dmocrats....
...and they base this typiclaly on the voter turnout of the last election -- the Obma election....with the uninspiring Republican candidate....
And to suggest that the turn-out in 2016 is going to in any way going to mirror the turnout of 2012 is pure and complete BULLSHIT...and the media knows it.
The media knows that when they examine Killary rallies versus Trump rallies that Trump is getting ORDERS OF MAGNITUDE greater attendance than Killary.
They know that both voter bases are extremely depressed...but that Trump has a blue-collar democrats drifting to his side...and the MEDIA IS IGNORING THIS...and instead if pretending that this is a 2012 turn-out year and ...
....and THERFORE the polling data is complete and utter crap.
Now you, my dear boy, are probably a one of those Democrats that can't imagine using logic and reason and facts when it contradicts yoru emotional held beliefs....I get it...
And you will be most likely *quite* surprised come election day.
Interesting thing happening starting last week. You know media doesn't want to be 12 points off in their predictions come election day....so anyone with a brain will have noticed that starting last week, even before the new FBI announcement that will sink Hillary....even then,k polls magiclaly started tightening up.
Where Hillary was up 12 points in one poll, for example, over a week in whcih essentially othign happened she is suddenyl only up 3.
WHY? You ask yourself...
Easy peasy, lemon squeezy...becuase in the last two weeks the corrupt media needs to shift from WE ARE TRYING TO PERSUADE YOUR VOTE and are falsely reporing data....to "WE ARE TRYING TO GET IT RIGHT SO WE STILL HAVE CREDIBILITY AFTER THE ELECTION"....
.....AND THUS they are throwing out their bogus models as the election draws near and will start reproting the ACTUAL polling numbers....and thus the magical "tightening of the plling numbers" as the election nears....
and now....because the Demoncrats nominated a criminal ....the polls are almost meaningless and the the election is wide open - the polls will not be able to predict the outcome.
ANOTHER point --- because the media has done such a fine job of bashing Trump, they have most likely ALSO influenced the polls such that people will LIE to pollsters and not admit they are voting for Trump....again makign the polling data they collect meaningless.
it is very possible that Trump has a Reagan-esque landslide - IN POPULAR AND ELEDCTORAL votes.
Just wait...
