The leftists that are realizing Biden is not capable are the same people that don’t notice stuff falling out of their pockets while walking, don’t feel a draft down their butt crack or cleavage when moving around, don’t look both ways when crossing streets.
They don’t recognize the Roomba behavior of Biden because they themselves are Roombas.
The NPCs have finally opened their eyes, but I don’t know if it is enough to shift the culture to save American freedom.
