Maybe I should have asked "should it be" instead of "can it be?" Doesn't the DoI set the principles that the Constitution was written to address? There wouldn't be a Constitution or a United States, as we know it, without the DoI.
true, as far as that goes.
however, you imply that the USC is an inevitable outgrowth of the DoI, and it is not.
The DoI, first and foremost, was justification for a war.
the USC is, first and foremost, the establishment of a federal republic on the ruins of a half-baked confederacy which was itself the first attempt to shape the peace after that war.
The constitutional convention was no placid circle of philosophers adducing from the DoI. The disagreements were often quite fundamental and heated enough to come to fisticuffs at least once IIRC.
Look, I know what you are trying to say, but I will not go there. We are a republic, ruled by law. The DoI has no legal weight. Thus, the glorious poetry of the DoI has no swaying legal authority, irrespective of its moral weight and probity.
