The jewel in the crown of this imperial presidency is of course the pre-holiday decision violate the text of the Patient Protection and Affordable Care Act and delay the employer mandate for Obamacare by a year.
People have started arguing about whether or not Article II, Section 3 of the Constitution applies to the president: "he shall take Care that the Laws be faithfully executed." After all, the government has gotten so big and complex that the president can't hope to dot every "i" and cross every "t" in every law that gets passed. He has to prioritize these things.
None of the above applies to Republican presidents, of course. They must obey the letter of the law, or else.
The Obama administration's flight from the law was analyzed and predicted half a century ago by Friedrich Hayek. The whole point of Hayek's thought, from The Road to Serfdom to the three volume Law, Legislation and Liberty was that big government had a fatal flaw in its heart. He argued that the complex responsibilities of modern government could not possibly be defined by cut-and-dried law. Big government necessarily required administrative flexibility if it was to work at all. But then, of course, it would no longer be a government of laws. That's why the welfare state was a road to serfdom, the feudal rule of the administrative bureaucrats.
To the young liberal like Ezra Klein, the extralegal antics of Obamacare are not a problem (H/T Reihan Salam). Congress should just come back for another try.
Congress should use the next year to improve the employer mandate. There are plenty of better ideas out there: The Senate Health Committee's bill used [blah blah blah]. The House bill tied [blah blah]. We can do better, and we should.
