PBS online poll posted...Sarah Palin is qualified?

[Karen]

Almost all online polls say, in the fine print, that "this is not a scientifically valid poll" as by their very nature, people can choose to vote in an online poll, or to ignore it entirely, every website has its own particular viewership demographics, and so the polls just make people feel like they are making a difference.

Having formerly worked in the market research field, I agree with Karen and ES, these are not valid polls and their results are meaningless.
