McClellan was the prototype for later generations of soft war Democrats, but to give him his due, he did stabilize the situation after 2nd Bull Run and he did well enough at Antietam to enable Lincoln to issue the Emancipation Proclamation, so he does earn some gratitude from Americans.
I see much similar between Mac and the lefty’s. Just as I see much similar between Bush 43 and Grant/Sherman. The only way to win is make them worry about what you are going to do, not worry at all about what they are going to do. No rest, no mercy, no quarter, anywhere, anytime. Just ask Al Qaeda who’d they rather fight against.
Very little in my mind.
