Why aren't there more calls for an end to this self-gaslighting?

Honestly, I find the Right wing media's tactic of promoting every verbal stumble of Biden as evidence that he's virtually a nursing home patient let loose on the Presidency is despicable.

Not because I think the likes of Hannity actually believe their fool's game (although, you don't know - never underestimate the ease with which repeatedly pretending something is true eventually convinces you it really is);  but because far too large a slab of the country genuinely is in the grip of a miasma of politically self serving conspiracy theories, and Murdoch and his employees must know that this is bad and dangerous for functioning democracy, and society as a whole. 

It's especially ridiculous when the people buying this genuinely think Trump was the smart one.  

The end of this can only come from prominent Republicans calling for it to end - but they are gutless.
