This is not generally true in the abstract, but the specific form of most Constitutional republics, including the US, is basically representative democracy, though sometimes (as in the US) with skewed voting power, and democratic values (coupled with fear of the volatility and excesses of direct or unconstrained democracy) was fairly central to the founding ideology of the United States.

No part of the US federal government is representative at this point. The Senate isn't by design, the house isn't because it's been capped, the presidency isn't by design.
