Last Wednesday, Trump’s negotiations with Nancy Pelosi and Charles Schumer began with his asking, “Will you agree to my wall?” without offering them any incentives to change their position. Pelosi refused to cave in, Trump said, “Then we have nothing to discuss” and just walked out. The very next day, as negotiations to break the partial government shutdown remained stalled, the President said, “I find China, frankly, in many ways to be far more honorable than Cryin’ Chuck and Nancy. I really do. I think that China is actually much easier to deal with than the opposition party.” After that, no one would say, “Gee, thanks for the put-down, Mr. President, let’s make a deal.” To be sure, congressional Democrats are being inflexible, but just as surely, Trump made it that much harder for them to change their positions.
