Everyone keeps trying to sugarcoat this. We all saw what we saw. Biden did fairly well overall, but there were moments that showed that he’s lost it at times. Being President ages you 4 years each year. He and Trump are both practically 100 at this point.
He needs to restore confidence by having a strong successor.
I remember an old school conspiracy theory about technology that could read tiny movements in your vocal cords that mimic thoughts.
While I doubt the technology to read minds remotely actually exists, I’m sure the techbros and their various financiers are working toward it.
