Quote from nutmeg:
We might forgive him for the mistake if he was honest person (honest mistake) but guess what? No one trusts Obama, he might have said that on purpose.
Quote from Tsing Tao:
The curious question is whether or not it appeared on a teleprompter or whether Obama was trying to speak without his teleprompter. Whenever he does that, he gets in trouble.
Obama is not a great orator like everyone gives him credit as. Lots of folks can speak well when the teleprompter is helping you. It's speaking on your own that truly defines great speakers.
