It perpetuates the delusion.
It’s the same delusion that people apply to the Democrats. Too many people choose to believe the Democrats are constantly “bumfuzzled” or “incompetent” or “ineffectual” or the numerous variations thereof that allow people to preserve their hope that THIS time the Lesser Evil Gambit will turn out OK, that the Democrats are not almost equally insane or evil and therefore Biden will do what he’s sort of a little but not really said he’ll do even though he and Pelosi and the other corporate Democrats have made it clear for decades that they believe and will do exactly the opposite, because they too are psychotic and psychopathic.
