In his prologue to “Rules for Radicals,” Alinsky made it clear that his book is about “the art of communication” and that the rules he enunciated don’t just work for radicals who want to tear down the system, but for any radicals “who want to change their world.” That, in sum, is exactly who Donald Trump is, and exactly why the Deep State and the Enduring Bureaucracy fear him. Trump understood innately the truth of Alinsky’s theorem that:

“… there are certain central concepts of action in human politics that operate regardless of the scene or the time. To know these is basic to a pragmatic attack on the system. These rules make the difference between being a realistic radical and being a rhetorical one who uses the tired old words and slogans…”

In this light, let’s consider that tweet about sanctuary cities again. Not only does it make Democrats live up to their own “open borders” rule book, it also demonstrates the truth of Alinsky’s Rule No. 9: “The threat is usually more terrifying than the thing itself.”
