I find this sort of scenario interesting as well. People tend to forget how ugly the Civil War got in the Midwest and underestimate Copperhead sympathies; Indiana, Kentucky, and Ohio especially.A relatively nasty possibility is if the CSA had found a way to stir up large-scale fifth columns in 1864 during the US Civil War instead of a bunch of fairly ineffectual terrorist attacks. That would have been quite horrific.

I've always wondered: in a "New England Secedes" scenario, would the Midwest follow the Easterners or remain in the Union?
