Whether you do or don't have the gist of why or how it was established, is important in understanding what the founders and framers of our country had in mind. There was serious concern back then that a direct election based on individual votes could lead to serious and perhaps irreversible changes to our government during trying times by some faction or segment of the population. Today, with TV, the press, and the Internet, we see public opinion being readily manipulated by what passes for journalism. Tell them this, but don't tell them that. Listen to this quote but let's not give you the context.
Now, this ever so much easier today than it was centuries ago. Yes, it's not democratic but the founders didn't set up a democracy. They set up a representative form of government. A republic. Of course with so many schools looking to eliminate civics and really digging into the history of this country, people are ill informed about why things were done.
I would argue that never before has there been a time when the electoral college is more important.
