evidence: The insurrection at the Capitol was of such grave consequence for liberal democracy and the rule of law that commentators have struggled ever since to find some historical precedent to provide context and understanding to a nation in a state of continuing crisis. Some thought immediately of the sack of the Capitol, in 1814, though the perpetrators then were foreign, soldiers of the British crown. Others have pointed to contested Presidential elections of the past—1824, 1876, 1960, 2000—but those ballots were certified, peacefully and lawfully, by Congress. None of the losers sought to foment an uprising or create a national insurgency. Compare Trump’s self-absorption and rage with Al Gore’s graceful acceptance of the Supreme Court’s decision handing the election to George W. Bush: "Tonight, for the sake of our unity as a people and the strength of our democracy, I offer my concession." [...] A civil war, in the nineteenth-century understanding of the term, is not at hand. But what makes the events of January 6, 2021, so alarming is that they were inspired and incited by the President of the United States, Donald Trump, who remains popular among so many Republicans and a contender to return to the White House.
