ok. i read the article, and it points out that the united states cannot actually default, unless it does so on purpose - which is a correction of the error that the right-wing demagogues were pushing through as political theatre in the fiscal cliff non-issue.
but, it doesn't change the fact that this is something that trump can't actually do. his claim that he can default on sovereign debt is about as ridiculous as promising a peace dividend of unicorns.
the correct conclusion from yglesias is that what it exposes is total ignorance. you, on the other hand, are just parroting the same, stupid right-wing scare-mongering you hear from the right on a fairly regular basis.
