MIAMI (AP) — Charlie Crist, the former Florida governor who switched from the Republican Party to Democrat, is working on a book that strongly criticizes the GOP’s conservative policies.

Dutton, an imprint of Penguin Random House, announced Wednesday it had acquired Crist’s “The Party’s Over: How the Extreme Right Hijacked the GOP and I became a Democrat.” The book is scheduled to be published in early 2014.

Crist was a Republican when elected governor of Florida, where he served from 2007 to 2011. But he became increasingly estranged from his party. In 2010, he ran as an independent in a three-way U.S. Senate race won by Republican Marco Rubio. Crist became a Democrat in 2012.
