I mentioned homelessness a while back and it's effect on then being able to be registered to vote. It seems great swathes of the population have been cast into the gutter in the US and then been forgotten. Someone will eventually make an effort to mobilise this mass of voters and seek to or at least promise 'change'. Depending how hungry that number are will help decide just who they'll be inclined to get behind. What could be the tinderbox for civil war in the US do you reckon?
That's hard due to the geography. I have said many times that if the political divide were North-South rather than urban-rural, we would be looking at secession or having the shooting start. Also, keep in mind that all of the US carriers (other than Reagan, which is based in Japan) are based in Democratic states. The Navy may lean Republican, but I also don't think they would much care for being arrested for treason by local authorities the next time they return to base for supplies and to see their families.
I think we're far more likely to see active defiance of the Supreme Court and the Justice Department at the state level than open war. I would expect to see the situation devolve into something more like the civil unrest and integration conflicts of the 1960s, if things get heated, until some sort of consensus can be found. One big question on the table would be where the Guard's loyalties would lie. If a president ordered a unit with a tradition of some independence like the Massachusetts or Pennsylvania National Guard to fire upon citizens of its own state trying to keep abortion clinics open, do they do it?
I'm not sure that they do, which is why Deng Xiaoping shipped in units from the provinces to overrun Tiananmen in 1989. He didn't trust the local Beijing troops to fire at the students in the square. Those logistics required controlling the pathways to
get to Beijing, which an extreme right-wing government would have difficulty accomplishing in the United States.
A hypothetical cryptofascist state, with a base of support in the center of the country and the Southeast, would face serious problems with maintaining its monopoly on the use of force.
