I'd figure less than 5% want a total ban.... with an additional 10-20% who are mostly ambivalent, but could be easily swayed to support such a ban
1. They pass a law making "reasonable" restrictions on firearm ownership
2. Something bad happens
3. They make another law with more restrictions
4. Something bad happens
5. They make a law with more restrictions
and so on and so on.
Like I've said before, the gun grabbers don't want to ban guns. They just want to prevent people who might use them from obtaining one.
The gun grabbers NEVER say that they want to ban all firearms because they LOVE the idea of government owning them but they hate the idea of civilians owning guns. For some ****ed up reason they figure that a government paycheck makes people pure of heart and conscience and that lack of a government paycheck makes people violent and incapable of self control.
Large numbers of people, though realistically, the constitution will never be amended in regards to the 2nd amendment.
