Americans absolutely love winner-takes-all narratives. They love it and they dread our "beta" democracies that cannot achieve anything.
They'd rather fall into Russian models of government where a single person can promise you the world and you give it the power to do so, rather than bother with things like "compromise" or "representation".
Re-electing somebody who openly attacked the institutions, instead of taking what happened on Jan 6th as a wake up call is the clear sign.
