A controversial book cover is the latest flashpoint to lay bare the divisions in the Democratic base over the Clinton candidacy. The forthcoming book, "My Turn," by Nation Magazine Contributing Editor Doug Henwood, critiques the former secretary of state's decades-long political career, calling out her foreign policy positions and purported connections to big-money interests, among other contentious points. 

And the book cover's flamboyant illustration – featuring a stoic Hillary Clinton, in a blood-red dress, pointing a gun at the reader – has sparked a heated debate among her supporters and detractors.
