Except the Democrats have said about as much handicapped stuff as Annoying Orange has since the election and also during it.
But the whole point of Snopes is to target claims/stories which are
in circulation on the internet. Something dumb that a Democratic state senator said gets far, far less traction on the internet than when Annoying Orange points to Pence and says he wants to hang gays. This is true based on simple inspection.
I'm not saying Democrats aren't prone to saying stupid stuff, since obviously they are. Politicians suck. But Snopes' whole deal is investigating claims that are being spread around via email or social media, and Annoying Orange dominates in that regard.
This is what my source was talking about; they cover conservative nonsense more than they do leftist nonsense because they are biased.
They don't 'cover' anything. Snopes is not a news source. They're a fact-checker that evaluates urban legends and stories spread on the internet. If something isn't virally spread around the internet, they usually won't touch it. Most stories which involve politics on the internet revolve around Annoying Orange, and most of these stories are negative and verifiable. If you take issue with this and think it casts a biased perspective, then the issue is endemic in the internet as a whole, not Snopes specifically.
