Is Barack Obama's dream, now a reality

[Byrd]

Seriously though, whether it's someone whispering in an earpiece, or a script on a teleprompter, or just intense coaching (or all three), I honestly do not believe that Biden is actually in charge (other than in name and title). 
(big snip)
Well, to my earlier post above, there are people controlling both Joe Biden and very carefully controlling his image, shaping people's opinion about Biden's competence.  They are consciously and knowingly presenting an image of Biden which is at odds with both the facts and reality.  This is control.  And, this is wrong.

I think we'll have to respectfully agree to disagree.

I worked with Alzheimers and dementia patients for awhile in my early work life, and do see a difference between normal aging and rapidly declining cognition.  The presidency is a stressful job, and it does take a terrible toll on anyone in office.  But when I compare Biden to Reagan (who was showing signs of his Alzheimers in office and who was being "helped" by others), I see a clear difference.

And yes, at least some footage was misrepresented or altered (the one where he turns and appears to walk away; a wider view shows that he turned to talk briefly to a skydiver.)

But... as I said, we both have our views and our experiences.  I respectfully disagree with  your conclusions.
