Check his history, dingdong basically exists to blame democrats for things republicans do. I'm not even sure they're US American.

All I can say is that they aren't interested in winning elections. Clearly. Their response is pathological, conspiratorial, and antisocial. There is a term which is becoming a bit of a trope, but its been gaining traction over the previous few years, which is simulacrum, a synthetic reality of ones own creation.

Corporate and "centrist" news sources spent decades building up a simulacra for mainstream dems and liberals to inhabit. And when you attack that fantastic world view, one totally unhinged from reality, they take that attack personally, because they've lost the attachment between their perceptions of how they think the world should be, and how the world actually is.
