Iowa is going to try to pass CC
We now have both houses of the legislature and the governor all Republican and openly talking about CC...one senator announced he has a bill ready. Until it's passed though, anything can happen. We may find some Republicans who voted for shall issue carry in the past getting cold feet. Only time will tell.
I am not in favor of national carry legislation. Once the swamp people get involved we could rue the day we went for national laws. I also would not trust a Supreme Court with only 5 pro- 2A members. Scalia himself endorsed reasonable gun laws in one of his opinions(Heller I believe).
Remember history shows we switch back and forth from Dems and Repubs. I would much rather rely on state lawmakers we can directly influence.
