In 2004, when the Swift Boat Vets first targeted Kerry, a debate erupted within his camp over whether it was better to ignore the book or to immediately strike back against it and bring it more attention. Early on, Kerry advisers chose the former path.
Obama advisers have concluded, however, that there's little to no chance that ignoring the book will deprive it of media oxygen. They are trying to strike the right balance, going on the offensive against the book without sparking even more media attention than it's getting already.
To that end, much of the pushback against the book is being done behind the scenes, through the dissemination of controversial quotes from Corsi's past and the planned extensive fact check.
Will it be enough? With Corsi already on record saying that he plans to collaborate with conservative groups to run ads, we'll soon find out.
