You conflate the Democratic Party with the idea of Democracy, even though there is not a 1-1 comparison. The US is representative democracy because that was the compromise reached between those who wanted rule by an “enlightened few” (aka an aristocracy), such as Alexander Hamilton, and those who wanted a more direct democracy, such as Thomas Jefferson.
The United States of America was founded as a republic, not a democracy: the word democracy is not even mentioned in the constitution of the United States of America, that guarantees every state of the American continent the republican form of government.
The Great Men treated democracy even worse:
“Democracy does not exist for a long time - it wastes, exhausts and destroys itself. There was never a democracy that didn’t kill itself”
Samuel Adams, the participant of the U. S. Constitutional Convention
"The American form of government is the republic. The true freedom does not exist either under despotism or excesses of democracy"
Alexander Hamilton, Secretary of the Treasury
"Democracy always leads to conflicts and instability, but never provides for the security of the citizens or their property. Usually it is very short at life, and very bloody at death"
James Madison, one of the authors of the U. S. Constitution
"Between republic and democracy there is the same difference as between order and chaos"
John Marshall, Chief Justice of the Supreme Court of the United States
"Democracy is the rule of mobs, tempted by newspaper editors"
Ralph Waldo Emerson
"Democracy - it’s the rule of the wishes of the mob, or to be exact ambitions and vices of its leaders. The Founding Fathers of our constitution created a republic, which is more different from a democracy, than a democracy is different from despotism "
Fischer Aims, U. S. Congressman
"I have been always sure, that democracy sooner or late will destroy freedom, or civilization, or both"
Thomas Macaulay, British Statesman
“Democracy - it’s the tyranny of majority, or more exact, the majority party, which through fraud or cohesion is manipulating the electoral process”
"The peoples, that accept democracy, yield its deadly fruits: enormous growth of public expenses; wars, inspired by the wishes of the mob, and not by intellect; unfavourable conditions of peace, threatening national interests and national sovereignty, lower housing prices and fewer civil rights. People grow tired of democratic politicians, coming in place of statesmen"
Benjamin Disraeli, British Statesman
"The acceptance of democracy by all European nations is deadly for the proper governorship, freedom, law, order, respect of authority and religion, and at the end will lead to chaos, out of which will appear the worldwide tyranny"
The Duke of Northumberland
Thus it is obvious, that modern democracy is nothing, but a dangerous mirage, that leads to millions of unnecessary victims, destruction and desolation of the United States of America.
