Not exactly science…
No, not for a nationwide civil war, but for potential “mostly peaceful protests” organized by the trained progressive socialist democrat agitators and activists during the extended ballot counting and challenging process. Seriously, political sentiment is a near-reliable indicator of risk, as we have seen from the 2016 presidential election cycle. Normally trustworthy and minimally corrupt intelligence and law enforcement agencies imploded, from the politically-appointed leadership to the deep-state bureaucracy. Few feared being held accountable for their criminal acts due to the widespread nature of the corruption that would see hundreds of individuals tried, convicted, and jailed.
Understanding the risk associated with the progressive socialist democrats is critical in preparing for an uncertain future. At the least, have enough food, water, cash, and toilet paper to avoid being in public areas during any period of unrest. Should this unrest move into the suburbs' residential areas, many will consider arson to be an existential threat to life and will respond accordingly – possibly with deadly force. For those who attempt to loot private residences, the result can be catastrophic and fatal as more and more homeowners have purchased weapons since 2016.
You may want to ensure you have an adequate supply of prescription medications on hand. Having a bug-out bag and a plan (including family reunification and communications) is necessary, especially if you have small children.
You may wish to develop a few reliable neighborhood sources for information as we can no longer trust the mainstream media – which has proven beyond a shadow of a doubt that they have been corrupted by corporate and political interests.
But remember, preppers often tend to assume worst-case scenarios and adjust their supplies and capabilities to be best prepared for these potential threats. This can lead to a form of paranoia and anxiety -- especially since most scenarios live mostly in their minds and are statistically unlikely to occur without an unanticipated "black swan" event.
It is almost a given that wing-nuts will capitalize on the discord, dissonance, and dissatisfaction promoted by the progressive socialist democrats over the past three-plus years. You can no longer count on the government to come to your rescue – as we have seen police officers stand down in the face of looting, arson, murder, mayhem, and even attacks on law enforcement officers themselves.
Take care of yourself, your family, and your neighborhood.
