Of course, I really don't think that there will be a split within the union even if the Tea Party gets it preferred candidate elected president next year. But in theory it is possible.
To bring about such a case something like the following would have to happen.
First, I suspect that this economic crises is a true depression and I believe that the policy that a GOP/Tea Party government would impose of continued and expanded austerity for most, but with continued rent granting to the well connected civilian and military contractors within the elite will worsen the depression to the point that as the 2014 midterm approaches the Tea Party/GOP will face being effectively wiped out of power or else patten unless they do something that may trigger either a succession such as claim a national security emergency and cancel the 2014 election. This could lead to something like the following.
In this worse case scenerio I could see CA, OR, WA, HA and likely NV forming a Republic of the Pacific.
It would be geographically coherent and relatively defendable.
The eastern succession would be a bit more problematic as certain midwestern states and I'm thinking mostly of Ohio and Indiana and maybe Iowa may play the role more that the border states in the CW 4T. Which is to say, there is an active succession movement within them but they either don't succeed or else they split themselves north/south along the
I-70 /
US Route 40 corredor, which has historically been a dividing line between the zones of northern and southern culture within the midwestern states.
This split could leave the eastern/midwestern group of succeeded state split thus likely leading to this area being the major focus of any military campaigns.
But enough of this. It is time to awaken from this nightmare to the grim enough reality that hopefully won't lead us there.
