(NEWSER) – It looks like Missouri is about to order the federal government to butt out in terms of gun laws. The state legislature appears to have the votes to override the governor's veto of a bill that nullifies all federal gun legislation, reports the New York Times. (The AP talks to several Democrats who confirm they will bow to their constituents' wishes on the matter and vote against their party's own governor next month.) Even if the legislation becomes law, however, critics don't think it stands a chance in the courts. Backers say an important principle is at stake: "It’s probably one of the best states’ rights issues that the country’s got going right now,” says a state GOP party official.
