I’ve actually already expressed MY position on the topic of what government can do. I also posted a link to the GOA, in which they discuss how the 14th amendment applies the 2nd amendment to the states.
What I don’t know is that you are correctly stating Cain’s position. Do you have a link to either a Cain quote or an article where Cain says what you claim he says?
Are Scalia, Thomas, Alito and Edwards wrong when they agree with Cain and say that the States have the legal authority to enact reasonable restrictions on firearms? It's a simple question. Are they all wrong? Is this what you believe?
