According to the Washington Post's Robert Kagan, the end has already begun:
The United States is heading into its greatest political and constitutional crisis since the Civil War, with a reasonable chance over the next three to four years of incidents of mass violence, a breakdown of federal authority, and the division of the country into warring red and blue enclaves. The warning signs may be obscured by the distractions of politics, the pandemic, the economy and global crises, and by wishful thinking and denial.
The stage is thus being set for chaos. Imagine weeks of competing mass protests across multiple states as lawmakers from both parties claim victory and charge the other with unconstitutional efforts to take power. Partisans on both sides are likely to be better armed and more willing to inflict harm than they were in 2020. Would governors call out the National Guard? Would President Biden nationalize the Guard and place it under his control, invoke the Insurrection Act, and send troops into Pennsylvania or Texas or Wisconsin to quell violent protests? Deploying federal power in the states would be decried as tyranny. Biden would find himself where other presidents have been — where Andrew Jackson was during the nullification crisis, or where Abraham Lincoln was after the South seceded — navigating without rules or precedents, making his own judgments about what constitutional powers he does and doesn’t have.
Most Americans — and all but a handful of politicians — have refused to take this possibility seriously enough to try to prevent it. As has so often been the case in other countries where fascist leaders arise, their would-be opponents are paralyzed in confusion and amazement at this charismatic authoritarian. They have followed the standard model of appeasement, which always begins with underestimation. The political and intellectual establishments in both parties have been underestimating Trump since he emerged on the scene in 2015. They underestimated the extent of his popularity and the strength of his hold on his followers; they underestimated his ability to take control of the Republican Party; and then they underestimated how far he was willing to go to retain power. The fact that he failed to overturn the 2020 election has reassured many that the American system remains secure, though it easily could have gone the other way — if Biden had not been safely ahead in all four states where the vote was close; if Trump had been more competent and more in control of the decision-makers in his administration, Congress and the states. As it was, Trump came close to bringing off a coup earlier this year. All that prevented it was a handful of state officials with notable courage and integrity, and the reluctance of two attorneys general and a vice president to obey orders they deemed inappropriate.
So, is the Republican Party a modern-day Catilinarian conspiracy? I guess we'll find out in the next few years. Should be exciting.
Excuse me while I Google a few things...
