No it isn't. But it is a good thing that we are a representative democracy as well as a constitutional republic.
The document which defines our Republic, the Constitution, begins with, "we the People" making it clear beyond question that the ultimate legitimacy for the Republic is the consent of the people, hence it is a democratic republic as well as a constitutional republic.
There are some issues that the Constitution places beyond the will of a strict democracy, such as rights of the people set forth in the Bill of Rights. Respecting other matters, such as the composition of the House of Representatives and now the Senate, the democratic will of the people in their various states is supreme providing their choice complies with the constitutional mandate for the office.
There are many other issues about which the Constitution is silent and presumably those issues are retained by the people to do their will according to the ninth and 10th amendments-or at least it was so when originally written and adopted.
We were never set up to act as a pure democracy designed by Rousseau for all to come together in concert and render up a unanimous agreement on the issues of the day. Even with the technology given us by the Internet, we do not act as a plebiscite democracy, rather we act as a representative democracy as defined by the Constitution. But a democracy nonetheless.
Thus, it is quite proper to describe our system as a democratic republic keeping in mind that it is also a constitutional republic.
