Which is why, instead of "democracy", it's more useful to quantify democratic. One traditional measure of such is the degree to which political power can be gained through free elections. But the research in TFA instead uses a novel measure: the weight a population has in its country's policymaking. Which yields fascinating results.

Because, per the linked research, in present-time USA that weight is ~zero.

Which is especially interesting considering the USA's narratives about itself. And how, it seems to me, its population is so invested in said narratives that it will defend those even in the face of contrary research. You'd think a culture so invested in its self-determination would be angry about this result and endeavor to do something about it.
