Thank goodness. When I heard about it, I feared that an angry, violent, Obama-hating ultraconservative was responsible. Which is to say, I thought maybe Joe Manchin had done it.

Alternate headline: “Obama apparently still has at least one supporter left.”

In video of the President, the book appears as little more than a blurr hurdling past his head to his left as he waved to the crowd on his right. It is not clear how close the book came to him but it is apparent the President does not notice it at all. The paperback seems to be coming from the direction of the audience penned in closest to the stage, not from the thousands of other spectators behind barricades farther back…

The US Secret Service found and interviewed the man who threw the book onstage. He was deemed to be an “overexhuberant” supporter who wanted the President to have a copy of a book he had written, according the Special Agent Edwin Donovan of the Secret Service in Washington. “He was deemed not to be a threat and was not arrested,” Donovan told ABC News.

I’ve searched high and low and can’t find the name of the guy who threw it or even the title of the book. Note to self: If you’re looking to exploit a presidential rally for promotional purposes, taking off your pants may be required.
