i bet lots of others feel the same....so...their numbers include all households called...but not everyone answered...

By the way, I am 60.

The older, less sophisticated (no Caller ID, older phones, etc.), plenty of time on their hands type of voter will pick up the phone.

Gallup claims to have adjusted to a 50-50 ratio, but I know of not one cell user who answers "Blocked" or "Unknown" calls.

And those pollsters aren't leaving call-back numbers.

which left no message on the answering machine, said answering machine I got in self defense from "Rachel" of cardmember services, who continues to call 3-4 times a week no matter how many times I " push 3 if you want to be removed from our calling list".
Pollsters are not gonna be responded to at all on my landline.
You would think that they would know sales calls have drastically limited pollster's ability to reach a household.

as far as polling goes. I don't pick up unrecognized numbers either.

15 years, cell only. I'm 58

The question is whether there is any bias in who no longer has a land line. The next question is whether there is any data on cultural and political differences between those with land lines and those who do not. I think that some clued in PoliSci or SocialSci researchers could have studied this, but have not heard anything. (Not that I am looking.)

The polls do seem to be all over the place, which leads me to conclude that they just don't have things right.

I do not think they are deliberately skewing their results. I think they want to get things right, but are using out-of-date models for their sampling and their analysis.

Cell phones is a very plausible source for such divergence, but without independent research indicating it, I would not want to make that a definite conclusion.

Somebody should study this.

Example: We live in a rural area with dangerous storm history.
So we have a cell and a landline.
Cell is often unreliable here.
Only 2 options for internet connection are telephone company and Mediacom cable.
People around here will not use Mediacom for ISP because it has proven to be too unreliable.
Thus many have landlines PLUS cell or have only landline.
This state is 80% rural.

I only got recent reliable cell. And only Oct 1, a 4G connection. But I haven't had a land line for years, in spite of previously dodgy cell service.

There is no other Inet here, other than dialup on land line or Sat. No cable here either.

I am in very rural MI, 50 mi N of Grand Rapids or so. More deer here than anything else.

I don't know about you, but when I answer a call and I hear a recorded voice instead of a live human, I hang up.

I read something earlier today, don't remember where, that suggested that there was a significant difference in results between robocall polls and polls done by live people.
