What would of happened if the constitution never got signed?
creativ13 [48]
If the Constitution had not been ratified the United States would not be the way it is now. Our rights that we have today are protected by the Constitution and if it had not been ratified we could not have been guaranteed the life that we have now (which most people around the globe wish to have.) The Constitution is a major part of U.S history and if it were not ratified the history of this country would have changed completely. Congress would have been working for the governments best interest and not the citizens' best interest. I also think that if the Constitution was never ratified, the U.S would have split into two separate nations- North and South. The North would have continued in the industry world while the South would have chosen the world of agriculture.
