These is no such thing as supporting the Second Amendment and then telling the states to decide. It's already settled at the federal level and the states cannot pass any laws which are in conflict with the Constitution. The Second Amendment is part of the Constitution, in case there are some that still don't acknowledge that.
Moreso, because the Second Amendment is mentioned specifically as an amendment not to be infringed as well as a law that states that the Constitution/Bill of Rights is the supreme law in spite of any Thing that the states might try to do concerning the right to keep and bear arms. Without equivocation.
American Citizens have been long-suffering regarding these attempts to immasculate the people. We haven't done anything about it at this late date because we are really curious to see what their end game plan is. Well, maybe just a little more than just curious.
Sorry, but that is what is happening and it will be accelerated once Obama or Clinton are elected. I’m glad I still live in a state where my 2A rights are upheld. Not everyone can say that in the US. Some communities ban gun ownership outright.
