California and Oregon: There was a lot of Southern sympathy in the lightly-settled Far West, especially California. Also, Breckinridge had an Oregonian as his running mate.
Breckinridge's running mate, Joseph Lane, was from Oregon as well (thus ironically the Southern Democratic ticket had no representation from any future Confederate state). Due to settlement patterns, Southern California's Anglo population was primarily Southern in origin thus making Los Angeles a decidedly pro-Confederate town.
This factors in the book version of God's and Generals, which in the beginning has Hancock stuck in Los Angeles, alone for the most part to guard a storehouse full of supplies against a town seething and angry. The nearest detachment is hundreds of miles away. Ironically the people who came to his rescue were Albert Sidney Johnston and Lewis Armistead, both of whom would later die fighting for he Confederacy, Armistead would do so charging Hancock's lines as part of Pickett's charge.
The book also displays similar chaos in Texas, where a then still Union Colonel Robert Edward Lee nearly gets lynched by an angry mob of secessionists. The irony!
