"Liberals founded this country..."
Hardly.
The 'Liberals" to whom you refer are the Socialist Party.
They didn't exist when this country was founded.
Fact:
The "Greatest Lie" is the one that the modern Liberals tell. They claim that those called Liberals today are the liberals who founded this great nation. Nothing could be further from the truth.
The Founders were'classical liberals,' whose vision included individualism, free markets, and limited constitutional government. That's why they wrote out a detailed Constitution.
a. Communist John Dewey, the one who corrupted education in this country, convinced the Socialist Party to change its name to 'Liberal.' And it's values and doctrines formed those called Liberals today.
The benefit to them, of course, is that the uninformed attribute the greatness of the Founders, of America, to them
Now....which 'Liberals' today espouse individualism, free markets, and limited constitutional government.
Certainly not the socialists/communists known as the Democrat Party
