I queried a number of American historians and constitutional scholars to see how they explain what should be an inexplicable response to an election conducted in a modern democracy — an election in which Republican victories up and down the ballot are accepted unquestioningly, while votes for president-elect Biden on the same ballots are not.

Many of those I questioned see this discrepancy as stemming from Trump’s individual personality and characterological deficiencies — what they call his narcissism and his sociopathy. Others offer a more starkly political interpretation: that the refusal to accept Biden’s victory stems from the frustration of a Republican Party struggling to remain competitive in the face of an increasingly multicultural electorate. In the end, it appears to be a mixture of both.

Many observers believe that the current situation presents a particularly dangerous mix, one that poses a potentially grave danger to American democracy.
