On January 9th, Mark Levin read excerpts out of his book Men In Black(pages 55-60, primarily), and it's a great illustration of how this all happens, step by step. In this, a few things stand out. Many of which Levin himself highlights. One thing that stands out to me is how Planned Parenthood employed the tactic of "arrestables", long before Lisa Fithian ever did. Notice how those fit together.
If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle - Sun Tzu (Chapter 3)
