The list of people he has been willing, even eager, to publicly attack includes not just Mitch McConnell, his latest target, but Jeff Sessions, Chuck Schumer, Paul D. Ryan, John McCain, Hillary Clinton, Bill Clinton and Barack Obama.
And don’t forget James B. Comey, Robert S. Mueller III, Andrew G. McCabe, Rod J. Rosenstein, John D. Podesta, Nancy Pelosi, Lisa Murkowski, Arnold Schwarzenegger, Rosie O’Donnell, Meryl Streep, the mayor of London and the cast of “Saturday Night Live.”
But for all of that feistiness ... there is one person who is definitely not on Mr. Trump’s target list: President Vladimir V. Putin of Russia.
