I’ve already answered this; you can’t punish officials for following the mandates of their own voters by not enforcing a law.
States, are under no obligation to enforce Federal laws. The only thing they may not do, is prevent Federal Authorities from enforcing the law themselves.
There are two Supreme Court cases on this, Printz v. United States (1997) and New York v. United States (1992). In both cases, Congress was trying to compel State Authorities to go along with enforcing a law, and the Supreme Court ruled against them.
Incidentally, It’s because of the precedent these decisions set, that States were able to reject large parts of Obamacare outright.
