Tom Woods explains that States can nullify (invalidate) unconstitutional federal laws, even if they are endorsed by the Supreme Court. In 2005, one State made a law that the federal government opposed and it went all the way to the Supreme Court. The Supreme Court predictably ruled that the state law was subordinate to "superior" federal law. But this State simply ignored the Supreme Court edict because there was so much public support in favor of the State law. Public opinion and support make it easier to resist federal tyranny.
