Well I've always liked the formulation "A Republic of Republics" as a short hand for the original design of the founders.
But obviously we've grown far from that over time, I'm not sure what simple terms I'd used to describe the current behemoth.
Let's get you on the record: how do you describe the current American form of government? It's certainly a lot less "republican" and a lot more "democratic" than it was in 1783.
(17th Amendment direct election of Senators, Progressive Era reforms, including citizen initiative, activist life-time tenure judges making laws up out of thin air, attempts to abolish the electoral college, executive orders in place of laws, administrative "laws" in place of legislation, fake treaties not ratified by the Senate, massive deconstruction of the Bill of Rights, etc.)
So you don't know, or won't say, what our form of government is. Duly noted.
Thanks for playing.
Constitutional Republic (as there are many republics in the world)...emphasis on Constitutional. Look it up.
If you can't figure that out on your own you're even more stupid than I originally concluded.
To answer you more directly...we're still a Constitutional Republic as the Constitution still exists, (doesn't it?) and it's still the law of the land (isn't it?).
When the Constitution is no longer the law of the land then we can have another discussion on the matter, though I'll probably be dead from having defended its elimination.
