jgcoastie, If your standard is one of constitutional carry, then Texas and Florida are in the bottom 46 somewhere.
IE that's the exception; not even 10% of the states, IIRC.
Please realize that I actually agree with your premise that open and concealed carry should be constitutionally protected.
I just don't agree that Florida, which IIRC was the first state to pass shall-issue, which helped domino a bunch of other states along, is anywhere close to Illinois, Maryland, etc when it comes to pain over guns.
Some states that, per your theoretical ranking, would have open carry (on the books) often don't seem to have it in practice. Look at threads on abuse of open carriers in CT, PA, and LA.
