Man I wish, but this is a pipe dream. This is the Golden Calf of concealed carry regulations because the opposition is so entrenched, emotional, and wide-spread. It would not just be the normal gun-control advocates but also the media (because it makes headlines due to the emotion of the topic) and parents who normally don't get involved would become so. The arguments against campus carry are extremely irrational but extremely effective when it comes to the general populace. Not that the general populace is irrational, they are merely only exposed to headlines and fire-breathing pundits because those fit the 30-second time slot on the local news much better than the complete and thorough argument that goes into campus carry. If the general population took the time to look at both sides of the argument instead of resorting to the easy stereotypes and one-line slogans we would see an interesting shift.
Anyways, the point is that if this ever passed we would know that we have finally tipped the public opinion in our favor in a huge way because it means that the biggest arguments against people carrying guns have been defeated in the eyes of the general public.
