This is what George Washington wanted, he said he opposed factionalism and parties as it weakened the unity of the Republic
Basically the same thing as a One party state so long as that one party is dedicated to the whole republic and its people's well-being (rather than the party being above and separate from the masses)
Two party system is the most undemocratic possible system
Multiparty parliamentary systems are also just a chaotic mess of petty difference
Unity cannot be achieved without the insistence upon oneness
