• There were emails in the DNC leaks that hinted at a suspiciously cozy relationship between the party and media organizations.
• During the DNC primary process, media reports often included superdelegates in Hillary's delegate count, making Bernie's case seem impossible. Media often failed to even mention the existence of Bernie Sanders in many cases, or calling him "unelectable" even while he was polling ahead of Hillary or Trump.
• In prior elections, some news channels may have gone as far as not even listing a second-place candidate they don't like in poll numbers.
• Voters can be influenced by a belief that their vote will be wasted by voting for someone who is not a "sure thing".
• Therefore, (assuming) the media manipulation or incompetence, DNC bias in favor of Hillary, and vote manipulation to give the impression of momentum to Hillary, even an insufficient number of delegates won by "cheating" could have swayed the election by second-order effects.
