Stay tuned. Obama is a constitutional scholar. The question is whether the next things to go will be the "signing statements" and other signals of the "Unitary Executive" theory that actually constitutes the kind of governmental power grab that impeachment was designed to remedy.
Or whether he'll use that power to take your guns away.
There is a 2001 Chicago television station taped interview of him discussing his views of the Constitution.
Here's an excerpt :
"....the Supreme Court never ventured into the issues of redistribution of wealth, and of more basic issues such as political and economic justice in society. To that extent, as radical as I think people try to characterize the Warren Court, it wasn't that radical. It didn't break free from the essential constraints that were placed by the Founding Fathers in the Constitution, at least as it's been interpreted, and the Warren Court interpreted in the same way, that generally the Constitution is a charter of negative liberties. Says what the states can't do to you. Says what the federal government can't do to you, but doesn't say what the federal government or state government must do on your behalf."
A scholar of Engels and Marx would be more accurate.
