The meme informed left-wing base doesn't care about what's actually true.
They're still running with "Vance has sex with couches" based on a total lie from a guy who calls himself @rickrudescalves on Twitter. For them, because it was a funny meme that denigrates their opponents it has power. And having power is all that matters.
The funny thing about that is if a left wing politician was caught having sex with a couch on a zoom call, they'd still vote for him...
Realistically, the fact that they've been cosplaying as Palestinians and calling for intifada all spring and summer tells you everything you need to know about how easy they are to mentally manipulate.
