Please. Some historical accuracy. The Politburo killed the last real Czar and his family. The Czar did not have a Politburo. The Soviets did not have a Czar. When the czarist government ruled Russia, there was only one Czar at a time. Under the Soviets, the Politburo was a permanent subcommittee of the Council of Ministers. All that said, yes, BO has created a Politburo of sorts outside of our Constitutional government, made up of people the Soviets would have called “commissars,” and later “ministers.” To call these people czars is a misnomer that leads to confused thinking.
You are right, and awhile back there was a somewhat more extensive article posted on this. I can only think that the terms “commissars” and “ministers” sound too real - people would sit up and take notice of them. But in America, the term "czar" is a faintly comic term. No one really believes we have actual Soviet-style bureaucrats here, and so the term is more easily taken lightly, or dismissed as hyperbole.
Which is, of course, exactly the public reaction that the commissars want.
