If we could know this will be the case, I would support it.
I would definitely support this.
I would wonder what would happen to those holding the current LTCH at that point, though. Would mine cease to be valid in states that currently honor it? Since I am legally still an Indiana resident, I can carry concealed on my LTCH while stationed in Florida; but if Indiana were to establish Constitutional Carry, I wouldn't be surprised if my "old" LTCH no longer let me carry here. (My situation notwithstanding, I would still support this.)
As long as I would not have to pay for it again, I just paid my fees not long ago.
