What is the Electoral College?
The Electoral College is a process, not a place. The Founding Fathers established it in the Constitution, in part, as a compromise between the election of the President by a vote in Congress and election of the President by a popular vote of qualified citizens.
You can read endlessly about this topic but it all comes down to this first question and answer.
The first consideration when considering the popular vote was how to get around it
It also states the election was based upon a Congressional vote and the popular vote. That's backwards but it exists.
footnote "qualified citizens"
that's almost democracy
Who or what could possibly outlast a person wealthy enough
to push the legal system to it's limits?
It's the legal system and it's not going anywhere
