James Comey better hope that there are no "tapes" of our conversations before he starts leaking to the press!— Donald J. Trump (@realDonaldTrump) May 12, 2017
This kind of bluffing and having it called is undoubtedly something Trump is used to in the business and real estate worlds. But in the political world, you are negotiating with the same people over and over again. And the lesson of the first two big congressional debates is that when Trump says a bill must contain XYZ, he doesn't really mean it; it's just posturing. And that doesn't bode well for future Trump demands.During the last government shutdown in 2013, when Republicans demanded defunding Obamacare, they were at least willing to follow through on that demand. The government was closed for more than two weeks before the GOP relented. That served notice to Democrats that Republicans were at the very least willing to go all-in on their strategy and follow through — that they weren't bluffing when they made such demands in order for a bill to pass. And that made their threats on other things seem more legitimate.Trump has shown no such inclination to make it so people take his demands at face value. And given what's happened in the first two legislative debates, the next time he draws a line in the sand, you can bet lawmakers know how easily it can be raked over.
