• We’re told the envelope given to Warren Beatty actually contained Nate Silver’s projection.

• To replace Michael Flynn as national-security adviser, Donald Trump selected someone uniquely suited for the position. H. R. McMaster isn’t just a courageous and innovative warrior (his victories in the Gulf War and the Iraq War are still studied today); he’s also a scholar who made his name with a book, Dereliction of Duty, that unsparingly exposed the failures that led to the American debacle in Vietnam. Central to his critique was the notion that American generals owed it to their commanders in chief not to roll over in the face of implausible or incompetent demands but instead to provide their best advice, no matter how unwelcome it might be. McMaster has spent a career winning battles and telling hard truths. That’s exactly the person to advise an inexperienced and sometimes impulsive president. May Trump heed his advice.
