Um, somebody needs to get these guys a history of the civil war, because nullification is basically just secession by a different name:
SHEP SMITH: Opponents of the health care law have come up with a new tactic to try block the whole thing. You'll recall 27 states, all of them with Republican leadership, are suing over the health care reform claiming it's unconstitutional. The case is likely headed to the Supreme Court eventually, but Republican lawmakers in Idaho say there is another way, a process called nullification that could, in theory, could allow them to override federal law. A few states have tried it over the years, but it's not worked. ...
SHANNON BREAM: It's a centuries-old maneuver that some states claim allow them to simply say, "Hey, I think what the federal government is asking our state to do is unconstitutional so we're not going to recognize that federal law."
SMITH: Other states are trying this same thing, right?
BREAM: Yeah, at our last count at least 12 states are considering some form of legislation just like Idaho's. Just yesterday a state house committee in Pennsylvania passed a bill that would essentially nullify just the individual mandate part of the federal health care law. A number of these states have already signed onto the court battles over this law, and lawmakers say this idea of nullification is just one more way they are going after it.
The immutable fact is that unless federal courts say a federal law is unconstitutional, then it's the law of the land. If you don't like the law, then go ahead and try to get Congress to change it. But whether or not Fox is willing to admit it, you can't just nullify it.
