What does the title have to do with the post? Unless I'm missing something, the post is not positing that someone is advocating a 4th branch of government but rather the existing branches are not following the Constitution.
The point of the article is that a 4th branch exists in effect if not in name, has existed because of the 1934 Humphrey’s Executor case and that it’s existence is in breech of the Constitution & the path for it’s existence should be eliminated.
