I can tell you there are very good reasons for not packing at a political event. I certainly wouldn't. Good way to get Oswalded.

There are plenty of crazoids running loose nowadays and if one of them decides to shoot a politician, I don't wanna even be near a gun lest some pusssy liberal screech that I did it. I can easily let the government be responsible for security at such an event and if I feel like I just gotta go, I will take my chances unarmed.
