In another post some time ago it was pointed out that the middle of the country controls the food and the distribution of same. Similarly the middle controls the flow of fuel and a good percentage of the production of energy.
So the elites decide they want to overthrow the elected President - as soon as that happens food, fuel and energy stop flowing.
The folks on the coasts will quickly melt from the heat if it is summer, freeze from the cold, not know how to get around without cars, buses and trains, and they will very rapidly descend into anarchy with the fittest and best equipped taking the food - the rest will starve to death.
No gunfire needs to happen. The military will be useless because 90% of them won’t engage their own citizens. National guard will walk away from their posts if ordered to engage their neighbors.
So the largest sufferers will be those who didn’t learn how to hunt and fish and build a fire to cook on. And the middle of the country has probably 95% of the non-military guns.
It will take years to rebuild but perhaps worth the effort.
Don’t forget that that the largest farms are actually owned by non-farmers. For example, IIRC, the largest privately owned farm in the world is owned by, and controlled by, a few offices in a building in New Jersey. The idea that middle America controls food production isn’t as true as it once was. It would be a very murky situation.
