In that two to four years, they could re pass the Assault weapons ban, and a lot more. The RINOs in the Senate would go along,and so would the President. This time they'd do it without a sunset, and it will be hell getting it repealed. Probably ban "sniper rifles" too.
Four years? More like four months. With the far left house, RINO senate and "conservative" president, I think things will be worse than even the worst Clinton years.
