Note - Obama has nothing to do with this, so don't automatically blame him. Congress makes the laws and it's everyone's fault for voting so many Democrats into office that it's lopsided.(IMO, both parties are equally wrong, but if they're in-fighting all the time, it slows down the damage they can do)
Of course, with 80 million people or more in the U.S. owning firearms(roughly half of all households!), it's political suicide for the Democrats to support this, so it's about 100% likely to die in committee.
