It only missed by three. It was the amendment closest to passing- evn more so than any of the "control" amendments. In a (D) controlled Senate.
If I'm being argumentative, it's because I enjoy the discussion - I hope you'll understand. In any case, an argument has been made that this bill was intended by the administration not so much to be enacted legislation, but to contain sufficient poison pills that would slide by the Senate and be rejected by the HoR, thus supplying the administration with political capital for the 2014 midterms. Thus, some horse-trading, permitting amendments which would be otherwise unconscionable to gun-grabbers was allowed to be voted up or down knowing that there was enough poison in the bill that the representatives would vote against the overall provisions even if one or more amendments were to our benefit.
