There are, evidently, several right wing politicians in the GOP now arguing for nullification. These are not just John Birchers sniping from their mother's basement, but elected members of Congress.
Perhaps this is good for me. I have had to do a little research on nullification beyond Calhoun's 19th century charge. I had not connected the South's "Southern Manifesto" in response to Brown v. Board as a new version of "nullification," though it clearly was. And, in fact, in Cooper v. Aaron (1958) the Supremes ruled that southerners could not simply ignore court rulings they did not like.
And that is what really bugs me about this. This is the right wing version of "I am taking my ball and going home." There is no compromise on issues, and no recognition that we can often--hell, always--find ourselves having to "agree to disagree." That means that I end up living with policies that I don't agree with. I don't agree with the Patriot Act, and I certainly don't agree with Bush and Obama's decision to continue mining our phone and internet transactions sans warrant. That doesn't mean that I withdraw from the union. It means that I continue to participate in a system where I don't always get my way.
But conservatives--or this branch now running the GOP--don't operate that way. They are the only ones who appreciate the constitution. They are the only ones loyal to the country. And if they don't get their way, they will show us by rejecting the very country they say they love more than we do.
