Barack Obama is not "eloquent".
Obama is very good at reading the words that are written for him by speechwriters on a Tele-Prompter.
Without his TelePrompter, Obama is a deer in the head lights with Hoof-in-Mouth Disease.
Even with his teleprompter, we still have the corpse-men gaffe.
You're right. Obama is really Ron Burgundy. Remember that movie? Towards the end, it was revealed that the only reason Ron Burgundy was successful was that he read well. He knew nothing about the news business, had no clue as to what went into producing a news story, or how to air a program, or the money/financing side of broadcasting. All he knew how to do was read from a teleprompter. It was what made him who he was. Basically, nothing.
