Specter to write a third book

Sen. Arlen Specter (Pa.) is facing a challenging primary race, and perhaps an even more challenging general election battle with Rep. Patrick Toomey (Pa.) this November. But that won't stop the 80-year-old cancer survivor from writing a book.

The Republican-turned-Democrat has seen the inside of both parties, and he told reporters Monday in Philadelphia that he's considering writing a book about his experience. Specter said he has some "special insights" that he could share in the book, though he declined to go into detail.

Specter is no stranger to the writing process, having previously penned two books. His first, in 2001, was "Passion for Truth: From Finding JFK's Single Bullet to Questioning Anita Hill to Impeaching Clinton." Seven years later he wrote, "Never Give In: Battling Cancer in the Senate."
