> France had true democracy in the late 18th century. It became a popularity contest to send political enemies to the guillotine.
That was not a "true" democracy. It was a mixture of anarchy (in that what government there was didn't have firm control of much of the country, or even of much of the forces nominally acting in its behalf) and oligarchical autocracy (in that what government did have firm control was run essentially by fiat of the Committee of Public Safety.)
Insofar as it was "democracy" at all, it was extremely indirect: electoral colleges were elected by the electorate (with ~11% turnout), who in turn elected delegates to the National Convention, which in turn appointed the Committee.
The US (either at the time or now) has much closer to "true democracy", by any reasonable definition, than Revolutionary France ever had.
