The democrats will implement a series of communist style laws that will restrict the sale of ammunition. They will also ramp up their efforts to restrict/ban the sale of semi-automatic weapons. While I am uncertain of how they will do it, they are evil and they are lawyers so I am confident they will find a way.
Because Obama is a proven pathological liar, I am expecting the absolute worst case scenario for America.
How they will do it is simple. They'll resubmit HR 1022, or something worse, early in the next Congress, say around January 7th or 8th, and pass it "just in time" to have it on B. Husein's desk say about January 21st.

Obama and Biden would repeal the Tiahrt Amendment, which restricts the ability of local law enforcement to access important gun trace information, and give police officers across the nation the tools they need to solve gun crimes and fight the illegal arms trade. Obama and Biden also favor commonsense measures that respect the Second Amendment rights of gun owners, while keeping guns away from children and from criminals. They support closing the gun show loophole and making guns in this country childproof. They also support making the expired federal Assault Weapons Ban permanent.
