Our founders VERY EXPLICITLY did NOT create a Democracy (some of the most-famous like Adams and Franklin cautioned strongly against it). They created a "Constitutional Republic" with "Democratic elections"
You do realize this is a talking point created by politically illiterate republican party activists who didn't like the fact that americas political system was in the countries name.
If you have elections, by definition, your a democracy. Thats all the word means.
If you dont have a monarch you are a republic.
