This has been a hot topic for a couple of years, the 10th Amendment has basically been abandoned for round figure 100 years and many states with the encouragement of the people have started to push back. At this time there is a law that has been passed in 7 states that is a 10th Amendment issue but is working with the 2nd Amendment. Check out
http://firearmsfreedomact.com/ There has not been any movement on this in quite a while, it was put on hold while the Nordyke case in California was completed, this was a roughly 10 year 2nd Amendment case heard in the same appelate court. Nordyke was settled last summer so we may get some movement in the courts once again on this.
Last year the NFOA proposed to a couple of Senators having a similar bill brought up here but due to the short session and knowing it would have no chance it was sidelined so Senators could introduce other bills they felt they could get passed. I will be bringing this back up as an issue with a couple of Senators shortly, the newly elected Senators are getting their briefings and training this week and will start getting set up next, then the fun starts.
