One of the big problems in CWII is that there are no geographical battle lines

Civil War II would probably look more like the English Civil War rather than the American Civil War. The English Civil War was generally fought along class lines and rural areas vs. cities. The industrial and merchant classes and most English cities favored Parliament, while the King mostly found support from the nobility and in rural communities. A hot CWII could see a return to classic siege warfare - the practice of surrounding a city for weeks or months, before launching the attack.

Leningrad comes to mind, although in the end the Germans lost. Difference is, in Leningrad you had a commissar on every block to keep the people motivated to stay the course or get a bullet to the mullet.
Our American city folk would fold after the first week. To lazy and to dependent of the Gubmint!
