Even as fond as he is of ruling by executive orders, he knows that he can't ban any class of guns without congress making it into law, so he's depending on congress to enact a ban that meets his approval. An “assault weapon” bill is sure to be introduced in congress ASAP and will probably pass in the Democrat controlled Senate, but I don't think it will make the grade in the GOP majority house. If it does a lot of GOP congresscritters will be out of a job after the 2014 election, and that would include mine if he votes for ANY new gun law. We are already denied too many (one is one too many) of our 2nd A rights by unconstitutional laws such as LBJ's 1968 Gun Control Act, enough is enough.
I will bet you that he will try to have someone in the House or Senate get a bill put on the debt limit vote which has a gun control bill. Obama will make it about the debt limit ceiling crises. To make this work he and Harry Reid will do what they can to let the debt ceiling for the government be hit so they can cry cuts are now coming, stir the hornets nest and the immediate need to address, put the bill in front of the house at midnight 3 minutes before they need to vote, just like they did earlier this month.
