The problem is that the map on the left is an old election map.
American Specialty Ammo posted this exact thing and later retracted it once this was pointed out.
Unfortunate. I suspect that the meme presented is probably close to the truth. Perhaps this will inspire someone (John Lott?) to gather the statistics for a similar map. The info is certainly available from DOJ on-line.
Too bad.
I’d love for it to be true.
Shouldn’t be hard to find a 2012 electoral map.
