One cannot deny that the year 1968 election was a horrible year for the United States, with Vietnam at its height, the assassinations of Robert Francis Kennedy and Martin Luther King Jr., the multitude of Race riots across the country combined with anti-war protests, the disaster that was the 1968 Democratic National Convention, the return of Richard Nixon to become President in one of the closest and most bitterly fought Presidential Elections in history, the popular rise of George Wallace who won 13.5% of the popular vote, 5 states, and 46 Electoral Votes, and the overall fall from trust in our institutions. So my challenge here, if you choose to accept it, is make 1968 so violent and so anarchic that the United States collapses into an actual civil war (as the 1861-1865 one can be more considered a failed War for Independence by the South rather than an actual civil war). The POD can be anytime between 1953-1968 and you can go however you wish to go about it. Have fun with this difficult, if probably impossible, challenge.
