Texas would've immediately invaded every state in the "Florida alliance" and incorporated them

California and Washington state would remain loyal, but Washington state would get jumped by the so-called "western forces", and would need to be saved by California, turning Oregon into a bloody battlezone in the process

Nevada would run to California to save itself from being eaten alive by the Dark Mormon Empire, who will sacrifice the entire population of Arizona to summon a massive daemon army to conquer Texas and California

The Feds would maintain control of the Tide Water, but there would be a massive insurgency in rural areas

Tennessee, Iowa, Missouri, New Mexico, Nebraska, Georgia, and Oregon would become battlezones where the majority of the "conventional" fighting is done, practically every other state will see rural vs urban insurgencies
