I put this up because the question was interesting and also implies a paradox. If the people who most love guns were offered this choice, the rest of us could pass real gun control. Voila.
There isn't much of a paradox there, because the guy with the gun still gets to vote.
The map is fairly accurate in one way, however. The greenest states have already given up much of their right to bear arms. However the reddest states still have just as much of a right to vote as the greenest states.
