A reader notes what was linked to but not explicitly stated in our previous post:

When I saw that video making the rounds yesterday, I didn't watch it.  Do you know why?  I'd already SEEN it.  It was part of a PBS Frontline documentary that came out in 2008.  It's available for instant streaming on Netflix.  Dud, indeed.

Money quote from PBS: "It’s been online at our site and on YouTube since [2008]." Another reader:

All that video proves to me is Obama was a good public speaker even 21 years ago, while he was still a student. With no teleprompter.
