I basically stopped reading Mr. Turley's article after reading his first myth refuting the idea that everything is impeachable. No, not everything is impeachable. The problem is that, as a consequence of Mr. Turley probably not understanding the federal government's constitutionally limited powers, particularly Section 8 of Article I, he is essentially clueless about Obama's constitutionally indefensible actions.
I believe that this article is a good presentation of the fundamental process of impeachment. I found its major shortcoming was the lack of discussion on the Senate’s role. Turley’s larger issue with the limitations of the Federal Government is a point well taken, but beyond the scope of this article.
