My view is that we have had the potential for a "constitutional crisis" for several years. In using those words I distinguish between normal (and healthy) partisan politics, and clear violations of the constitution, in particular the "signing statements" in which the Administration identifies parts of a law they will disregard.
This is a clear violation of the President's obligation under Aricle II that "he shall take care that the laws be faithfully executed," as well as his oath of office. However, there is no sign the Pelosi and company have the stomach for anything other than a two-year circus of hearings and headlines.
I couldn't find that particular column by Krugman, but in general I read him very carefully. He has the capacity to be very insightful but also so vitriolic that his underlying arguments and observations are obscured.
