This is NOT the 103rd Congress that passed AWB 1.0 in 1994. Even the 110th Congress was Dem majority and a AWB 2.0 sponsored by 4 Republicans didn't make it out of committee. The 111th super majority Congress that Obama brought in didn't do anything, either.
If the 112th/113th Republican Congress is willing to fall on their swords to protect tax rates for millionaires, many of whom don't support the Republicans -- I don't know how far they'll go to undermine the 2nd Amendment. I don't think they will go too far. Maybe mental health checks, a tax deduction for gun safes, Federal school safety standards. The question is if the 114th will see the return of Nancy Pelosi as Speaker (God forbid!) and that may be what this is all about.
True, Obama can do something with an executive order, but there are limits on what he can do that the courts won't void, and the next Republican president can just void the executive order.
My guess is that the disaster of Obamanomics will continue unabated and that he won't be awfully popular in 2014 -- but that's just my guess, and I remain amazed by what happened in November.
