How do they define "familiar with Snowden"? John Oliver's team interviewed numerous passers by in Times Square in New York and while many of them gave negative opinions, few of them demonstrated knowledge of what he revealed. Many thought he was related to Wikileaks or thought of him solely as "that guy who hurt our national security". When asked about the actual ramifications of Snowden's revelations (how they would feel about "dick pics" being seen by the government), nearly all of them had very negative opinions (which would likely affect their opinion of Snowden). Doesn't really affect Hillary's politics but still, if the media would actually inform the public about his revelations, things may change.
