Put another way: Mr. Obama proposes, Congress refuses, he does it anyway.

For example, Congress refused to pass Mr. Obama’s Dream Act, which would provide a path to citizenship for some not here legally. So Mr. Obama passed it himself with an executive order that directs officers to no longer deport certain illegal immigrants. This may be good or humane policy, yet there is no reading of “prosecutorial discretion” that allows for blanket immunity for entire classes of offenders.

Mr. Obama disagrees with federal law, which criminalizes the use of medical marijuana. Congress has not repealed the law. No matter. The president instructs his Justice Department not to prosecute transgressors. He disapproves of the federal Defense of Marriage Act, yet rather than get Congress to repeal it, he stops defending it in court. He dislikes provisions of the federal No Child Left Behind Act, so he asked Congress for fixes. That effort failed, so now his Education Department issues waivers that are patently inconsistent with the statute.
