They must be seriously infiltrated with liberals and RINOs. What rational objection did they have? I cannot think of any, except that they wish to delegitimize the ownership and carrying of guns, which implies that they wish to delegitimize the Constitution, and all that is implied by that.
I believe their opposition is that they believe it will be a detriment to attracting industry to the state. Oklahoma is a very conservative state, but we do have our share of RINOs and crony capitalists.
