It's heartening to see that some progressives have principles. Bruce Ackerman criticized President George W. Bush, and now he criticizes President Barack Obama.
Addendum: The following paragraph is revealing:
Mr. Bauer is not the only administration lawyer to conclude that the billion-dollar bombing campaign in Libya does not amount to “hostilities” under the War Powers Act. The State Department’s legal adviser and former Yale Law School dean, Harold H. Koh, has also taken this position. This is surprising, since Mr. Koh’s legal scholarship over the years has been highly critical of presidential overreach on matters of national security, emphasizing the importance of Congress’s constitutional powers over war and peace.
Remember the name "Harold Koh." He has been mentioned as a Supreme Court nominee. This case shows that he is a political hack devoid of principles and reeking of hypocrisy.
