Q Poll Landline Methodology

[Rule of Claw]

Landline numbers and cell phone numbers are scheduled for 4+ call attempts. When calling
landlines interviewers ask to speak with the adult member of the household having the
next birthday. Interviews are conducted on cell phones with both cell only and dual owner
respondents. The complete land and cell sample is weighted to National Health Interview
Survey estimates for [land only/cell only/dual owner] households.

6.5 percent.

Yes it matters. It explains "tight" polls vs. blowouts. Who will be right? The ones that get the correct sample of white college vs. non.

But this I do know-there won't be as much "missing" white non-college using only cell phones or online as "missing" white college with no landlines and a 36.7 percent sample.

So on balance a high landline sample could lean a poll several points red.

1. Generational

I don't think there are many generations under the baby boomers that still have land lines.

That being said republicans aren't doing as well with the 65+ crowd this election cycle.
