Hollywood might have catapulted Barack Obama into stardom in 2008, but journalist and author Jason Mattera is out with a new book he hopes will have voters questioning some of the president's most strident supporters.

"If anyone can get Obama re-elected, it is Hollywood," Mattera told Whispers. "These are master entertainers. They know how to reach at people's emotions. Conservatives should be vigilant. That is why we have the book. It is like an ammunition stockpile."
