I agree with Tom. It is very possible that without Clement making the NRA's argument, the 2A would never have been incorporated. Also, most of the folks angry at the NRA for not arguing incorporation via the Privileges and Immunities Clause are the same folks who get steamed at any hint the NRA is involved in anything else (whether true or not). The NRA is about gun rights, not any other rights that would have been sucked up through the P&I Clause.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
