On the other hand, Mr. Trump has reportedly mused that impeachment could be the ticket to his re-election in 2020 if it looks like Democrats over-reached. Well, then, here’s the ultimate Trump-friendly reason to spare Mr. Rosenstein: It’s way better reality TV. Maybe it’s just a coincidence that this meeting is happening on the same day as the Senate Judiciary Committee hearing featuring Supreme Court nominee Brett Kavanaugh and Christine Blasey Ford, the woman who accused him of sexually assaulting her in high school. Maybe “The Apprentice” was lightly edited to reflect actual events and not amp up the drama. Mr. Trump has the opportunity here to upstage (or at least distract attention from) a hearing that nearly 60 percent of Americans say they will be following closely or very closely, according to an NPR/PBS NewsHour/Marist poll. If Mr. Trump fires Mr. Rosenstein on the same day, he either overshadows a strong performance by his Supreme Court nominee or amplifies a bad one. Taking the unexpected step of leaving Mr. Rosenstein in office allows him a chance to make his point, demonstrate to his supporters who is in charge (him not some Sessions underling) and distract from the obvious truth that the Senate GOP leadership has no intention whatsoever to let whatever happens on Thursday prevent its rush to a Kavanaugh confirmation vote. Any good reality TV show needs a shocking twist. Here’s Mr. Trump’s chance to provide one.
