Ezra Klein is the Editor-in-Chief of Vox, founder of JournoList, contributor to WaPo, Bloomberg News, and MSNBC, and an all-around liberal icon. A few years ago he said and wrote that the Constitution was written 100 years ago. This level of ignorance is expected from modern libs. What is surprising is that Mr. Klein has graduated from the University of California with a major in Political Science! If the lib icons have no idea about the subjects they supposedly studied, is it any surprise that they know nothing about physics, biology, and engineering?
