Even the best surveys these days only manage to get about 10 percent of people on the phone, while the shoddy ones might struggle to get 3 or 5 percent of voters to return their calls. These percentages have fallen precipitously over the past two decades.
Polling firms are hoping that the 10 percent of people that they do reach are representative of the 90 percent that they dont, but who will nevertheless vote. But there are no guarantees of this, and it is really something of a leap of faith.

So, irrespective of everything else in this article, every prediction we've bee seeing involving polls, whether pro-Obama or pro-Romney, is based essentially, not just on a cross-section of the populace that gets called, but on 10% (or 5%, or 3%) of that cross-section that responds? Given that, it's amazing that polls come anywhere near predicting the final result.

Heck the 7-11 soda-cup survey has never been off by as much as 1% and has Obama up by 57-43.

There's a difference in the demographic, which resullts in different results.

(1,922 posts)How many times/how often do you answer an Unknown Caller on your cell?
Do you think Gallup actually leaves a call-back number?
Heck no.
Also, the odds-makers have real skin in the game (dollars).
I pay no attention to any poll.
Well, unless it is one that calls me The Coolest Guy in Town.
