It has "only" been Referred to Committee, that means they pretty much have not even even looked at it yet, more bills die in committee and in huge numbers then anywhere else. I have seen a lot of legislation that go to committee and get buried.
The make up of the committee is pretty moderate with a handful that are anti-gun, the Committee chairs is "anti-gun", but the majority of this sub-committee seems pretty moderate and conservative.
Not to mention this is just a House Bill, don't they have to set up a similar Senate bill to move this forward. I would really take notice is a Senate Bill started developing and I would and will take interest once it gets refered "from" committee in its current form, but again...they will need the Senate to really move forward.
And thus...that is why I say...I don't think this is going to be a big priority for the next administration.
