In what ways does the U.S. Presidency support and limit the formation of an ideal democracy?

In order to be ideal, a democracy needs to be perfectly structured without flaws in the system. That seems to be out of reach in real life because nothing is ever ideal. The U.S. presidency limits the formation of an ideal democracy because all some people have conflicting ideas and opinions. A democracy means for the people by the people, however there is no way that all of the people in the U.S. can agree on one thing and have the same opinions on issues.  One of the concerns that came up after the Revolutionary War in 1776 was that "it did not provide for a single official responsible for directing the executive branch who would be independent of Congress (The politics of power, p.175).  I like this cartoon because it represents all of the issues that block any country from reaching an ideal democracy.  The importance of the presidency was greatly established due to the fact that without a president the "government could otherwise drift and be stalemated in a system of checks and balances" (The politics of power, p. 178).
