As far as I'm concerned, that is a separate subject from immigration policy and border security. I understand that there is some at least tangential relationship between arming the narco-criminals and border security (and between arming the narco-criminals, then sending in your own military to do battle with them), but for the most part, the issues are separable.
As a standard for supporting a candidate, "better than the ones who sell guns into Mexico so they can strip US citizens of the RKBA" is very low.
I think heads should roll, literally, for that. Death penalty - and I'd let Mexico impose it on our federal government officials and employees who set up and executed the program.
I'll be pleasantly surprised if there is a single criminal conviction; and I doubt Holder or Obama will be damaged by the scandal. Congress is worse than worthless, it is damaging to the country's well-being.
I see you live in Maine so it’s understandable that you see things differently.
National security is threatened by the unprotected Mexican border — this involves illegal migration into the U.S. and crime.
A sealed border will combat both issues.
Perry wants a sealed border and he does not believe in amnesty.
He recognizes that the crime along the border hurts both countries and actions by the administration have exacerbated the situation — lit a fire.
