He wants you to believe that he tried, but he just couldn't get the left wing to fall for it. But anybody who has used Facebook as seen how popular AddictingInfo-org is, and it is an overtly left wing fake news site. It's not remotely the only one.
The fake news reporting is itself filled with fake news. And it's easy to find marks because after the election, many people need to find a scapegoat so they are turning off their critical faculties. The current complaining about fake news is a mirror image of the right's disrespect of the "mainstream" media. For instance all the reporting on the Trump-Russia covert email server communication matches the formula for fake news, it took a nugget of truth, twisted it, and tried to ride the lie long enough that by the time it was exposed as nothing, the election would be over and the "damage" done. But it wasn't fake news I guess because the outlet has to be small and the target and victim were reversed. Anybody looking at that should reasonably be upset about "fake news" but it's categorically ignored by the left. You are not inhumanly wise and immune to the effects of incentivized bias.
