The President dodged a, er, book the other day:
Obama has book thrown at him at Philadelphia rally | Mail Online: "This is the astonishing moment a book was apparently hurled at the head of President Barack Obama during a campaign rally in Philadelphia.
The flying missile narrowly missed hitting the President yesterday.
It is not clear what the book was, where it came from in the crowd, or why it was thrown at Mr Obama - who did not appear to notice the danger"
Which is sort of a metaphor for his whole presidency.
