The post is based upon an ACLU Poll but does not link to the primary source--bad journalism IMHO.<p>The details of how the question was posed can have a huge impact on the result. To evaluate the reliability of the poll you have to know the questions asked and the methodology. Even then it is a difficult task.<p>Likewise, the method of choosing the sample to poll needs to be described in detail. Self-selected sample don't ever produce reliable results. Biased samples reflect their biases.<p>Given the prevalence of weasel words about the Snowden awareness of the sample (a paean to journalistic accuracy), I suspect that none of those polled had any deep knowledge of what Snowden revealed and that the results reflect media evaluation rather than a reasoned opinion.
