There was a time when anyone with a 6th grade education or higher understood the completely opposite concepts and why the Founding Fathers INTENTIONALLY designed a “REPUBLIC”!
I ask liberals where word Democracy appears in the Constitution. They can't - it doesn't. (I joke and say it is right next to the 'right' to abortion.)
But Article IV 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.
