You may be right on that point I concede; there would probably still be a significant gun lobby at each convention, but in the wake of the Civil War (which I don't see regular conventions averting, save for if the Senate is removed) I think many might have seen the benefits of a regular standing army of some bulk (as the US has today), rather than hastily improvised militias, as the Amendment allows for and supports:
- The Version as Ratified by the States.A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.
The Right to bear arms is a consequence of the militias and if no need was seen of them the right may not have stood; but I grant it could resurface as a right in itself rather than a right by necessity, as it is now (as I see it), at one of the Conventions.
I any case it couldn't hurt, the Electoral College should be on the chopping board by now. I just think people seem to heed the Constitution as a document more than the spirit of the Constitution as a principle, which I view to be a grave error. But I stray from the subject at hand.
