Whatever the intentions...
and, really, who knows at this point, and really who cares when it comes to it. The damage or the potential of the ambiguities has been realized over a very long period. While I do not have religious like feelings towards the Founders, I do think they were reared in and highly sophisticated in the use of their language. Consequently where they are explicit, I am willing to believe they were being explicit, where ambiguous (even if only apparently so) I am willing to believe it was by design. They wanted to 'form a more perfect union' for instance-clearly more perfect than the Articles of Confederation was able to deliver-but why form a union at all (perfect or otherwise) if there is no intention of making the new government of that union effective. Given that the Constitution is, amongst other things, an example of horse trading, and given that it was cobbled together by politicians, what makes us believe that those who wanted it open ended didn't get some of what they wanted and those who wanted it more limited got some of theirs?
When I read the document (which I do frequently) that is how it appears to me. All the recent hermeneutics notwithstanding, this is not some holy document, but very much a piece of compromise-probably-and in the case of Franklin- very likely flawed but with as much chance of being right as being wrong, to paraphrase him.
Limited government like small government, is a relative thing, How limited? There are those who will claim they know to a certainty; but there are those who know to a certainty, even unto murder, the real intentions of God too.
