On often trod What-If, basically the Rebs are doing good in '64, say a successful Gettysburg or something far worse. Tired of war, the coalition Union Party under Lincoln fractures with the Democrats reuniting somewhat calling for a negotiated peace.
My real question who could be a credible Democrat candidate in 1864? Do the Peace Democrats have a decent man or maybe a War Democrat who changes sides after military reversals.
Pretty vague but curious, throw knowledge and suggestion at my face.
