Former Republican Sen. Lincoln Chafee will discuss and sign his new memoir at 7 p.m. on April 3 at the Warwick Barnes & Noble. The book is titled Against the Tide: How a Compliant Congress Empowered a Reckless President.

The title is fitting for Chafee, who spent much of his career swimming against his own party. He finally left the GOP last summer and joined the ranks of the unaffiliated. And should anyone doubt that he’s no longer a Republican, he publicly endorsed Democrat Barack Obama for president last month, annoying many in the GOP because the endorsement came hours before a Warwick rally for John McCain.

The science of selling books begins with creating a buzz, and the news release announcing Chafee’s book-signing swings hard for it, highlighting his endorsement of Obama. “This is sure to only cause more furor around the man who left his party and vehemently spoke out against the backdoor politics and deals that led a nation to follow a President without all of the necessary proof before heading to war,” it reads.

Chafee wrote the book with former Journal reporter Tony DePaul, one of the more talented scribblers to pass through these halls.
