If the Democrats manage to cheat their way to victory in the Georgia Senate elections, then I suspect they will try to pack the Supreme Court within their first year in power. It would be rather difficult to achieve some of their more radical policies with conservatives in the majority in the court and they have promised a lot to their radical wing.
Of course if they do that then it is almost inevitable that the Union will dissolve in some form of another. It might take a few months for things to get rolling, but in the wake of the Supreme Court being packed I would expect to see conservative areas of the country engage in mass civil disobedience, nullification, and ultimately demand secession.
Whether that would dissolve into civil war at that point is hard to say. It's certainly possible that cooler heads on the leftist's side would permit a peaceful breakup, considering that the Democrat's leadership would be unlikely to survive a civil war regardless of the outcome.
While a successful peaceful secession wouldn't be easy, especial since the Red Blue split is mostly an urban versus rural thing, it would certainly be better than a civil war. With how interlocked our economy is, especially in regards to food, a significant portion of the population would almost die in any sort of internal war. And given how dependent some parts of the world are on our food exports it is likely that mass starvation would break out in many foreign countries.
So yes, I dread this year. And I dread next year even more.
