Will certainly sit just like everything else that's been sent to the senate....
Everyone is holding their breath for the super-committee to finish.
Recall that (last?) year they almost got a similar bill attached in the Senate to a "must pass".
Regardless, politically we now have a fresh up and down vote on record to tell the anti-gun types by, hopefully we can get it kicked to the floor in the Senate for the same purpose.
Also, if the Administration speaks out it will get them on record, if "in favor" why wouldn't the Senate pass it? If "against" it confirms the administration is not "pro-gun".
