I disagree. He isn't all that intelligent, and as for articulate, he is just a good teleprompter reader. Listen to him when he's off prompter. Ever wonder why his college transcripts are harder to find than a virgin in Hollywood? Sure he was President of the Harvard Law Review - but try finding one thing he's written. No, he isn't all that intelligent - he just shows well (or used to).
Applying the standards that liberals have used, this is my conclusion:
Reagan was a dimwit because he used cue cards
Bush was a idiot because he pronounce nuclear (NUK-CLAR)
Now Obama has declared there are 57 states and the army corps has changed to the army corpse!
So it is official by liberal standards Obama is a frigging moron.
