> Then you should know that phone polls aren't pure probability samples, either, because plenty of us don't own landlines (pollsters aren't allowed to call cell phones, which means people like me are totally unreachable).

Then there are people like me, who own a landline and use it as something to attach TEH INTARWEB to. I honestly don't think I've answered the phone in seven years, so I'm totally unreachable also (sorry, but I'm not going to call the pollster back even assuming he DOES leave a message).

> Virtually every national poll done today is done over the phone or, increasingly, the Internet. They are then weighted to try and overcome the problem. Do you think it makes the polls invalid?

Yes. All polls that do not involve sending a dude around the country in a van to ask everybody directly are invalid.
