An interesting, even if not surprising, finding buried in this Public Policy Polling survey on airlines:
16% of Americans think you should be able to bring your gun onto a plane. There’s a large partisan divide on the issue with 30% of Republicans but only 6% of Democrats supportive of guns on planes. We also asked about expanded background checks on this poll and a plurality of the people opposed to them also think you should be able to bring your gun on the plane.
Many Republicans have called for armed passengers following 9/11, believing this would help prevent terrorists from taking over airplanes. (Actually it might, but it might also increase the number of flights which do not reach their destination.)
Republicans tend to argue that those at risk of violence should be carrying guns for protection. Well, not always. I can’t find any Republicans saying that Trayvon Martin would have been safer if he was carrying a gun.
Update: Shortly after posting this I found this related article: Guns Are For White People.
