CMV: a republic is too flawed if a system of government for a nation as large and heterogenous as the United States.

Republics work very well in small, homogenous societies. Where basic unifying principles among the people are shared. Whether those principles are solely ideological, or are manifested in other ways (shared ethnicity, culture, religion, etc.) 

A republic may have been a desirable form of government in 1793, when we were 13, relatively small, and relatively homogenous colonies. 

But in 2020 the United States spans the entirety of North America. Our culture is vastly different depending on where you are, and we have no unifying principle. Something all Americans can look at each other and say “we share this”

In short, a republic is not an appropriate form of government for a geographically large, and ethnically and culturally heterogenous society like the United States.

Which is why we are also a federation of states and below that multiple municipal governments. The US has a very bottom up structure of government.

Yes we do. It's called the US Constitution. The entire nation and its structure are all heavily based on the framework of the constitution and it the principles that inspired it.
