Maybe the prompter should be President?
The idiots that voted for the Kenyan Klown didn't vote for the prompter.
All of which assumes that a president (be it Obama or somebody else) has no opinion other than what appears on the teleprompter.
IMO, there's nothing intrinsically wrong with a president using a prompter -- it's just a tool, and if it permits more accurate or complete answers, I'd be all for it.
Where it can go awry is if it becomes an "instrument of theatre." I can definitely see Obama using it that way.
