And on the EO. Are you sure about that? Did you notice the new ATF mandates on reporting on dealers in only border states? They (the administration) pulled that right out of their a$$, and IIRC no EO required. What's next that will just happen by edict?
Yes. Fairly certain on the EO front. EO's can only be used to give direction to an agency of the Executive branch operating within the constraints of authority given that agency by the Constitution/Legislative branch.
In otherwords, Obama can order a review of certain firearms and how they meet the "sporting" definition of a law regarding the importation of weapons because Congress gave the executive branch the authority to control the importation of weapons...but he can not sign an EO ordering a domestic manufacturing ban of semi-auto AR-15s because the executive branch doesn't have that authority.
ATF pulled their reporting stunt based, arguably, off of their existing authority to monitor and regulate FFLs. The policy change did not change or create law and has withstood court challenges.
All that being said, I'm not going all in with a paycheck or anything because I know they are right now pouring over the books to find any and all loopholes they can find to make a show-dent with an EO or agency policy change.
