While this topic has been covered, it is now time to put real "meat on the bones" to explain why polling in this year's presidential contest, not just nationally but in many of the battleground states, may be off when compared to the actual results.

Looking at a vast array of polls coming out just two weeks before the presidential election, critically important states such as Florida and Ohio appear to be close and anyone's guess as to the final result. And while some national surveys, such as Gallup, have shown Republican nominee Mitt Romney running ahead of President Obama by several points, most have the race very tight, and a few have Obama leading. Let's examine one poll, released as a series of continuing surveys by a large television network joining with a respected national newspaper.

This particular poll, conducted Oct. 17-20, has no intended bias, since it is conducted jointly by both a Republican- and a Democrat-oriented polling firm. But read on, and you will quickly realize how the old style of polling and the way many polls "weight" raw results may be setting us up for one of the biggest polling disasters since the infamous polling blunders that led to the "Dewey Defeats Truman" headline blunder of 1948.

Consider the following, using the above-referenced survey as just an example of how many "big league" polls are conducted. Let's look first at the questions asked of those who bother to answer the poll.

First, the poll has between 30 and 40 questions in it, depending on which questions a respondent is asked. Considering the fact that most questions take at least 30 seconds to read and some questions ask up to seven sub-questions, at bare minimum it takes 20 minutes to answer and more likely (just a guess) 30 minutes or more for some folks. So what hardworking, productive member of a family, taking care of a business, house or family, has time to spare for such an opus? Likely not the type that fits the profile of a Romney voter.

And it's hard to imagine a modern and sane cellphone user staying on the line so long -- but this poll includes 300 of them. Yeah, that fits my concept of cell users ... not.

But let's continue. This particular survey asks plenty of questions, such as whether the person answering the poll approves or disapproves of President Obama's job performance and how they feel about both Obama and Romney.
