A little reading our Founders...
I’ve read Founding Father quotes and things to the contrary. I will have to find them. On travel now with no access to my library.
If you have people you are going to have differing points of view - factions. Aristotle points this out! (and as the joke goes if you have 3 Jews in a political process you will have 5 political parties! - told to me by an Israeli!)
All you have to do is look at the history, the political battles have always whittled it down to 2 parties. Their names don’t matter. Third & 4th parties are usually one issue parties and they end up being absorbed into the main parties (or take them over! GOP absorbed the Whigs after they imploded!) We have a sort of “winner take all system” at least until the next election. If a major party implodes then another party moves up but we still end up with two! Why ? Because it always comes down to - (I’ll just set the extreme ends!) Government control of the citizenry to little government control of the citizenry. Unfortunately that mean is moving toward full control end.
Back to the idea of multiple party government. The only way that would work again is in parliamentary system. It’s no panacea! Look at Germany! All the European states have difficulty making decisions & governing.
