Former Speaker of the House Newt Gingrich (R-Ga.) spoke his mind in an explosive, exclusive interview that’s only in my new book, Subversion Inc.: How Obama’s ACORN Red Shirts are Still Terrorizing and Ripping Off American Taxpayers.

Gingrich criticized Sarah Palin and Rudy Giuliani for treating Barack Obama’s background in radical left-wing community organizing as a joke.

From Subversion Inc.:

In his opinion it was a strategic blunder for Palin and Giuliani to mock community organizing at the 2008 Republican national convention. The mockery was “not helpful” because “it trivialized Obama and Obama is not a trivial person,” Gingrich said. “Obama is the most serious radical threat to traditional America ever to occupy the White House.” It would have been better if Republican leaders “had gotten up and said, here is what he was teaching, and they had taken the audience through five principles of [Rules for Radicals author Saul] Alinsky.” Such a discussion “would have sobered the country. It wasn’t a funny thing. It was a profound insight into how radical Obama is.”
