Not at all, though it does show that the declaration occurred and changed upon the individual actions of the separate states, not some unstated and unsupported legal concept of "the Union" that supposedly predates it.
Do a google search on the Stan Klos website and look for the Declaration of Independence page. I recall there is a image which shows the text of the Lee resolution for Independence (July 2), with the clerk's tally of the votes [all "A" (aye), no "N" (nay)].
That was the Lee resolution though, which incidentally Lee himself later described as an act of 13 separate states. The subject of our discussion is the Declaration itself. I'll ask you again. Prior to New York's decision to join the Declaration do you know of any version of that document that states itself to have been unanimous?
And for Lee's statements see his Federal Farmer letters in which he repeatedly refers to the government created under the DoI as one of "thirteen republics."
