Clinton Poll Problem

Questions raised about Zogby poll on Hillary's chances - AMERICAblog: A great nation deserves the truth: "Yesterday we reported that Zogby had a new poll showing Hillary losing to all of the major Republican presidential candidates. Since that time, there's been a lot of discussion as to whether Zogby's poll was a valid poll. Apparently, Zogby's polled people who opted in to a 'please poll me' email list that he runs. Normally polls are done with random voters from around the country, not people who opt in to an email list. For starters, I'd be concerned that known partisans would opt-in to this list with the intent of totally skewing its results - i.e., it might not be a representative cross-section of random voters. Pollster.com has far more about the poll and its problems."
