Also, back then there was still a lot of disagreement about how the US would work. Was it going to operate be a single, unified country or would it be more like an EU style organization with a unified defense? IE Federalists vs Anti-Federalists? The electoral college was a compromise to let each state run its own elections and only franchise who they wanted. It’s important to remember that the US was not founded as a universal suffrage nation, and has only slowly and after much painful internal struggle expanded civil rights.
