Here is the difference:
Cheney can listen to Obama and think on his feet to adjust his speech to address the errors.
Obama’s teleprompters cannot work as quickly to tell him what to say if his speech followed Cheney’s.
GIGO.
Cheney doesn’t even have to listen to Obama’s speech. Cheney alreayd knows what to do and say and how to do and say it. :) He thinks with his mind and not a teleprompter.
