Depends on the types of people who are likely to give up their phone number for national political polling reasons, and in that subset, I'd think that is hardly random.
- mpyne 13y agoThey don't go out and canvass for phone numbers first. If they don't include cell phone numbers it's possible to bias more towards older persons, but that wouldn't invalidate the survey either.
- cinquemb 13y agoThe survey itself? Probably not. The conclusion most people are likely to draw from it and apply it overarchingly, that is what I question.
