Obama knows he can't get an AWB through congress. This whole issue is political posturing, to take our minds off of the fact the economy is in the toilet, foreign policy is in total disarray, and the country is going to hell in general. Ufortunately, we've also got some political posturing on our side as well. When state legislatures pass bills to stop federal laws from being enforced, it's just political posturing as well. We fought a civil war over this issue 150 years ago. The federal government will always prevail over state govrnment. Posturing not withstanding. When a sheriff says he will refuse to enforce federal laws, he is well within his rights. When he says he will arrest BATF agents for enforcing them, he's blowing smoke.
