I’m not a constitutional scholar but I take issue with that characterization.

Federalist #10 by James Madison is all about factions, how they are inevitable, and how the system of government should be structured so that their self interests balance out for the good of the nation. Madison wrote the Virginia Plan which proposed the three branches of government and he wrote down exactly what his thinking was at the time. For most of the 18th century the British empire was a single party state ruled by the Whigs which is what they were trying to avoid by explicitly allowing room for many factions.
