WRONG. WE are a Democratic Republic. "Democracy" is simply Greek for "people rule". It just makes We The People the ultimate source of authority in a government. It says nothing about requiring a majority or even how power is distributed from the people. In our case, we are a representative democracy where the people elect people to make laws on our behalf.
If we were "NOT a Democracy, but a Republic", we'd live in a country like Cuba.
You better go read the history of this nation’s founding, and specifically, you had best read the arguments put forth in the Federalist Papers. You are 100 percent wrong.
