I guess the Obama’s Netflix version of a grid down situation is the racist whitephobia gay version of the book Patriots or One Second After. Newt Gingrich wrote the forward on One Second After:

Newt Gingrich, William Forstchen’s co-author on a number of alternate history novels, sets the tone for One Second After with his forward to the book. “Though this book is a work of fiction, it is also a work of fact. Perhaps a future history, that should be thought provoking and yes even terrifying for all of us.”

If I remember correctly McCain brought up EMP attacks in the senate back then.
