This is an undated photo of Union Gen. George Brinton McClellan, posing with his gloved right hand tucked inside his waistcoat. Author William B. Styple's latest book, "McClellan's Other Story", focuses on the role of a Cincinnati politician as adviser to Gen. McClellan, who ran against Abraham Lincoln for president in 1864. Long before Mitt Romney and Barack Obama wrestled over Ohio, it was a political battleground state for Lincoln. (AP Photo/Mathew B. Brady)
