News organizations use [these polls] to declare a winner, sometimes when few of the actual returns from the voting precincts have been recorded. This practice has raised concerns, especially since the major television networks all rely on [this] data from the same source. … While [these polls] are often accurate, if the sample of voters is unrepresentative of the population, the survey questions are poorly written, or interviewers are not trained to properly administer the poll, the results can be wrong, as was the case in the 2000 presidential election. —From Saylor. org's "Understanding Diverse Populations and Public Opinion," Comparative Politics, 2012
