If George Bush was a butcher of the English language for his mispronunciations, usually in the heat of the moment, then Obama is more guilty. His is a constant grammatical mistake.
Using the GWB standard for determining intellect, I hereby declare that Obama is an idiot.
Obama's new Secretary of Education, Arne Duncan, said, "gave my sister and I..."
He was reading from prepared remarks, presumably written by him, upon his acceptance of the nomination.
Perhaps he believed he was quoting Shakespeare?
