Washington’s words confirm this Republic.
We do not have a pure democracy in the USA, as some politicians are spouting off to eliminate the Electoral College. It’s in place for an important reason.
The founders set us up as a Republic based upon Democracy. Its a hybrid.
As they cross checked the three branches of power (executive, legislative and judicial), they also did with majority (democracy) and representative (republic) control.
This is also why we have an electoral college to balance out the popular vote. Furthermore, we have 2 groups which make up Congress, the House (based on population of each state) and the Senate (2 per state).
