It opens a whole can of worms. If an illegal is detained, if he is kept too long or the Feds don't take him as the Obama administration is no longer going to assist Arizona in dealing with illegals, are they going to file a "profiling" lawsuit? Does it open the border with Arizona further allowing the invasion of illegals with the Feds not helping? Is crime going to increase? Is the medical and welfare system going to be drained so much that it bankrupts Arizona? Should the 30 states which backed Arizona succeed from the union? Like someone said, the union was created for joint security (borders). Otherwise they were independent states or countries. How can anyone in their right mind vote for this guy again? Clinton would have been better for the Democrats. Obama is a communist and wants the nation to fail so he can be a little dictator and bring about his "socialist" utopia. Forget individual responsibility, forget individual freedoms. The almighty state will take care of you, and tell YOU what to do.
