Unde malum et quare? Where does evil come from and why does it exist? That has always been one of the big questions; over at Bloomberg News, former White House macher and Samantha Power super-spouse Cass Sunstein says he’s solved at least one part of the riddle: he’s figured out the from whence and why of the Tea Party.

It is everything Occupy Wall Street hoped to become, and the MSM did everything possible to make OWS flourish. It was hailed as a movement of historic impact, the start of a global trend, one of those epochal developments after which nothing will ever be the same—and it guttered out ignominiously.

After playing an important role in US policy in the Middle East and East Asia, he chaired the international committee that established the United Nations. On leaving the government in 1946 he went on to head the Carnegie Endowment for International Peace, then as now one of the most respected institutions of the foreign policy establishment....
