There is a great misunderstanding taking place, i hear many media types make the mistake, democratic, democraticlly. Our nation is not a democracy.
We actually use an electorial system of voting, not, democratically elected officials.
Correct we are a republic and the constitution assures the federal government will ensure to each state a republican form of government:
Article 4 (section 4)
“The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened) against domestic Violence.”
Absolutely correct....however America is a "constitutional republic" while being a 'representative republic".... representative democracy is the only democracy that’s around at any state or national level.
