The Electoral College is the key to the entire analysis and not just an isolated reform.
The Electoral College began as a device of the one percent. Only one percent of the people (at the time of the Civil War) owned slaves. Through the virtual representation of the Electoral College slaves created votes which their white slave masters cast to determine the highest office of the nation. Control of the Presidency gave the Slave Power control over the Supreme Court as well. That’s how Dred Scott got written.
