This is WELL worth the 10 minutes of your day to watch. A great perspective.
It was clear that the Founders feared Democracy, and this helps explain the reasons, in simple terms. This is why, for example, we must consider the 17th Amendment for repeal (in case you weren’t sure why some people have been making an argument for it lately). The US Constitution did not intend for the general population to elect its Senators (only their Representatives). The States, through their Republican-designed legislatures, were supposed to.
If we forget what our freedom is, and where it comes from, and what the limits of our government are, we will have failed to "keep" this Republic.
