The New Republic was founded by Herbert Croly, a "Progressive" who believed that the Constitution should be abolished in favor of the will of governing elites. Here is what Virginia Postrel wrote about him several years ago:
Crolyism overturned the ideal of limited government in favor of a combination of elite power — commissions to regulate and plan — and mass democracy.... Frustrated with constitutional limits, Croly wrote, “It remains ... true ... that every popular government should in the end, and after a necessarily prolonged deliberation, possess the power of taking any action, which, in the opinion of a decisive majority of the people, is demanded by the public welfare.” This statement, while extreme, pretty much sums up today’s governing philosophy.
So, keep in mind that this is the philosophy behind TNR. It is a view that the political elite need to tell everyone else what to do, and use lethal force against people who resist.
