Last week, SCOTUSBlog had a podcast interview with legal scholar Erwin Chemerinsky, discussing his new book The Conservative Assault on the Constitution. The blog has asked Chemerinsky some follow-up questions, and his responses  are worth reading.
For instance, he discusses the concept of a living Constitution and the hypocrisy behind the Right's claims of a consistent approach to judging cases.
Q. Within the context of the "conservative assault" you discuss in the book, can you please define the terms "living constitution" and "strict constructionist"?
- Everyone is a strict constructionist in that everyone believes that the text of the Constitution should be followed where it is clear. But the phrase "strict constructionist" was coined by Richard Nixon to refer to something more ideological: Justices who followed the conservative approach to interpreting constitutional provisions. Interestingly, conservatives are not strict constructionists in interpreting the Second Amendment. There conservatives read the Second Amendment as if it simply said "the right of the people to keep and bear arms shall not be infringed." They ignore the first half of the Amendment which speaks of the right existing for the purpose of having a well-regulated militia.
A belief in a "living Constitution" rejects the notion that the meaning of a constitutional provision is the same in 2011 as when it was adopted. A living Constitution says that in interpreting the Constitution, Justices and judges should consider history, tradition, precedent, and modern needs. There always has been a living Constitution and hopefully always will be. The opposite of a living Constitution is a dead Constitution and no society can be governed under that.
He also discusses how self-professed conservative "originalists" are selective in when they pay attention to original intent.
Q. You write in your book that "it is clear that conservatives often abandon the original-meaning approach when it does not serve their ideological purposes." Can you please elaborate - perhaps by providing an example or two?
- Affirmative action. I am skeptical that we can ever really know the original intent or meaning for a constitutional provision. But if ever it is clear, it is that the drafters of the equal protection clause of the Fourteenth Amendment intended to allow race-conscious programs of the sort that today we call affirmative action. The Congress that ratified the Fourteenth Amendment adopted many such programs. Yet originalist Justices, like Antonin Scalia and Clarence Thomas, pay no attention to this history in condemning affirmative action. Another example is campaign finance. There is absolutely no indication that the drafters of the First Amendment intended to protect the speech of corporations (that did not occur for the first time until 1978) or spending in election campaigns. But conservative Justices nonetheless find a First Amendment right for corporations to engage in unlimited expenditures in campaigns.
Of course, that is a reference to Citizens United, where the aggressively activist Roberts Court handed our elections over to powerful corporate interests. There is a direct line from that case to the new corporate-friendly gang that will be running the House of Representatives  for the next two years.
Who sits on the Court has consequences for us all.
