You are not thinking things thru here. The Red states are going to go ape if Shitlery steals the election. The Blue states would be happy. Why would a red state go into chaotic unrest if the Governor and legislature would be willing to secede? Why would there be war?
Almost every red state has a few pockets of blue; I think your point about secession is important, I also think that secession might not be necessary, just a massive Red State unwillingness to go along with any federal laws or regulations. Although I keep seeing history from 1860-1865. Secession did not work out well the first time.
