The question with President Donald Trump is competence. Just like the Trump travel ban's difficulties resulting from a poorly planned policy, that was publicly rushed to create the illusion of an administration "accomplishing things," there is much about the Republican health care proposal (American Health Care Act) that can be perceived the same way.
Trump campaigned for president by promising that he was going to replace the "disastrous" Obamacare legislation with something "terrific" that simultaneously was less expensive, provided more complete coverage, and was available to all; conditions irreconcilable on their face. The reality, we learned, satisfied none of these conditions and was estimated to leave some 24 million citizens without coverage after 10 years.
Trump is not the first president to make false claims, nor to be intellectually shallow and in over his head. The more serious problem is that he has surrounded himself with sycophantic yes-men who are equally inexperienced in the ways of Washington, and it isn't clear that he listens to them anyway. What should one expect when the senior adviser's goal is to "deconstruct the administrative state"?
