One of the strangest features of the inauguration was various politicians' boasting of the U.S.'s long run of peaceful, democratic transitions. “We do this in a peaceful, orderly way,” Sen. Lamar Alexander (R-TN) said in his introduction. “There is no mob, no coup, no insurrection. This is a moment when millions stop and watch. A moment most of us always will remember. A moment that is the most conspicuous and enduring symbol of our democracy.”
Not to rain on everybody's parade, but this is just about the least special feature of American democracy. You know who else has regular, peaceful transitions of power? Lots of countries:
And this isn't even including countries with a history of successful, peaceful transition without democratic procedures. The tally for Portugal in the above graph, for instance, doesn't include peaceful transitions undertaken during the Estado Novo dictatorial system, such as when Marcelo Caetano took over for long-time ruler António de Oliveira Salazar in 1968. Nor does the above graph include, say, the peaceful transition from Mao Zedong to Hua Guofeng to Jiang Zemin to Hu Jintao to Xi Jinping in China — not exactly democratic, but certainly peaceful and orderly!
All of which is to say that "we move between rulers without killing each other" isn't exactly the highest standard to which to hold American democracy.
