I think you are wrong about him getting what he wants, what he wants is this to go away, he really has no benefit in continuing this any further. He got the stage for a few weeks handed this off to joe, and really didn't do much after all was said and done.
I don't think "as I said before" that this is going anyware. Unless some crazy person does another school shooting, it will die in Congress with some renewed Background checks and possiblly a temporary 10 round restriction on magazines, which will get overturned on some techicality by a smart attorney, or the Supreme court, "if they are in the mood to hear it"
If you notice he kept saying that Congress has to OK this, he said it several times. It was an executive action, not an executive order. Going to the bathroom is an executive action, when the PODUS does it, so don't allow yourself to be mislead by the language they use.
Just like yesterday when a Congresswoman said, Imported assault weapons. It's a tricky situation.
