The word is out about Trump.
The teabaggers must be saying, "The force is weak with this one."
Why did Trump badmouth teleprompters? Because the Teabaggers badmouthed them.
The teleprompter is of course, a very useful way for a speaker to deliver precisely the speech he wants to deliver, without overshooting the time limits.
What happens when a speaker tries to memorize a stump speech? We had a great example of that when Marco Rubio kept repeating the same dumb phrase about Obama and Christie called him on it. And everyone remembers Rubio's grab for his water bottle better than anything he said.
Leadership requires excellence. Effective speaking is a serious and important part of leadership.
A teleprompter is a tool for achieving excellence, just as a good set of socket wrenches are the sign of a good mechanic, If you see a mechanic trying to get it done with pliers or vise-grips, consider taking the car to someone else.
The teleprompter screen also can deflect bullets.
