I don’t think that the various machinations in the implementation of ObamaCare suggest that the law is a “train wreck”. That the claim is being made is easy enough to find so I won’t bother to link to any of them here. Just Google “train wreck”. At the top of the list of results will be posts, articles, etc. either claiming or denying that it’s a train wreck.
What I do think they reflect is a very different view of law and government than I’m comfortable with. Essentially, it’s “how to sculpt a statue of a rabbit” as applied to government. Take a block of stone (the law as enacted) and then cut away anything that doesn’t contribute to a general impression of rabbititity (exercise executive discretion).
