This isn't an immigration question. It is a question of states rights and federal overreach. The Supreme Court has held that the federal government cannot force state and local governments to enforce federal law by mandate. Nor can they withhold federal funds based on not enforcing federal law unless the enforcement was specifically required when the funding was offered. Even in those circumstances, the state must have the opportunity to deny the funding if they don't support the attached laws. None of these apply here. This is simply unconstitutional.
