I think we have a double edged sword here. On one hand I think it's awesome to be so brazen as to pack your AR15 to a presidential speech, nothing says F-U more than that. They have their 2nd amendment rights on display, and that is very cool.

On the other hand I see far more negatives to doing this:
  • The left media will label these folks as 'gun nuts', just another public image of rednecks and their weapons (or rednecks clinging to their religion and guns, that was it...)
  • Because of how much people SO over-react to issues, this could lead to a new gun control law that says that no weapons are allowed within 600 yards of the president (or some such thing) and make these types of folks move too far away to be noticed. That's a double whammy, because it's another gun control law and another nail in the coffin
  • We could find that places of public venue, such as this was, may invoke private rules about banning guns - yet one more place we cannot carry a weapon
  • This could be one huge "see I told you so" that prompts Obooboo, the biggest gun hater elected, to say "yup, you're right, it's time to put gun control on the menu since this is front and center in American's minds"
Of course none of this may happen, but it's just some of the things that COULD happen with such an out-of-touch left looking on. One exception, however, might be if OB was talking about gun control, then the damage is done and you might as well show up in support of no more bans (but again, that could backfire even worse). Taking guns to a health care debate.....I just don't know.
