They fucked up the design if they didn’t want factions (yes, a common term at the time for what we call parties) and did so in a way that makes it nearly impossible to fix in practice.
The electoral college also never functioned the way it was supposed to, as in, broke almost immediately.
They also knew the Supreme Court was horrifyingly dangerous but their best answer was “uh, ignore them sometimes I guess?” Another couple sentences outlining a panel system instead of permanent Supreme Court members (which aren’t required by the constitution—the court is, fixed permanent members of it are not) could have done a lot to fix that flaw, though may have been impractical at the time due to travel and communication times before the train and telegraph.
It was an OK try for an early democratic constitutional state, but we really could have benefitted from a third attempt.
