Not long ago, Barack Obama's peers knew him as a moderate. As a constitutional law professor, Obama generally subscribed to the dominant progressive ideology at Harvard Law School, but voiced a strong belief in separation of powers and other checks on the executive branch. Many hoped he might become the first civil libertarian president. Now, even liberal law professors (not to mention liberal Supreme Court justices) are questioning the legal reasoning behind the Obama administration’s increasingly brazen edicts. David Bernstein, a constitutional law professor at George Mason University, has documented the worst of these abuses power in his new book, “Lawless: The Obama Administration’s Unprecedented Assault on the Constitution and the Rule of Law” – drone strikes without Congressional approval are only the tip of the iceberg. Regardless of your political tribe, you must listen to Bernstein’s warning. Obama supporters should be especially wary – after all, who knows who will be wielding these expanded powers down the road?
