Here is the reply I got from PBS:
Thank you for writing to PBS regarding the Web poll that asks, “Do you think Sarah Palin is qualified to serve as Vice President of the United States?” The poll is part of the companion site for NOW, one of PBS’ award-winning public affairs program. The series creates a poll each week that is based on the news to solicit opinions from our Web visitors about current issues. This particular question appeared the week of the Republican National Convention, when Sarah Palin was nominated, and it was designed to reflect a question that many were asking at that time. It is no longer on the Web site home page. The weekly online poll reflects the interest and enthusiasm visitors to pbs.org feel about a particular topic; it is not a scientific measurement of opinion. Due to massive accessing of the poll that was compromising the overall performance of pbs.org, a “cookie” system has been implemented on the Palin question. Therefore, as of September 23rd, a user can only vote once, on one computer. The current poll, also taken from the most recent headlines, is “Who [Senator McCain or Senator Obama] do you trust more to fix the nation’s economic mess.” Visitors can cast their vote in this poll at http://www.pbs.org/now/. We appreciate your interest in PBS and our online content. Sincerely,MaryPBS Viewer Services
