The Feds would be in no more control the they are issuing drivers licenses. Resisting urge for sarcasm. Oh, I can't resist. Are you a Congressman, voting nay on something you have not read. Could not help myself. ;-)
Are you an idiot not to know what allowing the Feds to have anything to do with a states issue can bring?
So let's think a moment. I know it might be hard for you, but try.
Say this amendment did pass....hooray!!!!! We can carry anywhere we want if the law in that state has a CCW provision!!! YAY!!!!!
Congress then comes along and says...."You know, there are too many variation among the states for CCW....we can do better. And since we are going to write the uniform laws for the nation, maybe we should have the records of those who have permits now and determine by OUR standards if they should be allowed to carry. Maybe we should know what they are carrying and have some way to track that weapon and ammunition."
Now, you MIGHT think I'm being a little paranoid. If history has taught us anything, and you seemed to have missed Civics in the public school you went to, but government that wants to 'help', usually wants control.
