I'll role play, I am Romney POTUS. This not a new AWB, it is the same ban which was enacted in 1994 and expired in 2004. Congress has not made any changes to the original ban except make it permanent. I did not request this legislation, but as you know I do support it for the same reasons I supported the Massachusetts's AWB, and will sign it into law.
You cannot trust Mitt as POTUS. Mitt ignores the Second Amendment, especially the part "shall not be infringed"
If that frightens you, I would suggest that just to calm your nerves, you should go buy whatever weapon you wanted that was banned by the AWB now, while it’s legal.
After all, AWB did not prohibited OWNING the guns, just BUYING them. Unlike the ban on civilians owning any new machine guns, which is a ban on ownership itself, not just purchase.
