Right now I’m seeing a combination: an Orban- or Putin-style illiberal sham democracy locking the federal/central government into effective one-party sado-populist rule by the GOP (with the Dem establishment settling for the table scraps as an even more hapless and neutered official opposition); certain states (like California) or counties or municipalities trying to resist its dictates through policy and legislation; and regions (e.g. the “State of Jefferson”) or neighbourhoods or individuals within those areas sympathetic to the central government responding with targeted blockades, sabotage of infrastructure, assassinations, bombings, etc; the central government will overtly excuse and sometimes covertly support such terrorism; it will also step in to arrest and imprison any Navalny-like figures and outlaw or hijack any organisation that poses a serious threat to its rule.
That scenario isn’t too far off from what’s happening now. It just formalises and intensifies it.
