Donald Trump is terrified
   His lies have begun to backfire, and he’s running scared
We’ve been dealing with Trump’s lies all wrong. We’ve been totaling them up — 
6,420 over 649 days,  according to the Washington Post! We’ve been parsing and categorizing  them — Trump’s statements are regularly found “false,” or “misleading,”  or it “needs context,” or it “lacks evidence,” or it’s “exaggerated,” or  a claim “contradicts earlier statements.” We’ve been comparing his  firehose of lies to the scant misstatements by past presidents —  remember how Republicans reacted when during the fight over healthcare,  Obama said “you can keep your doctor”? We caught him in a lie! Yipee! 
 We’ve been fretting about what to call them — The New York Times famously made news with the first time 
they used the word “lie”  in September, 2016 to describe Trump’s “birther” claims about President  Obama, and since then has been sparing in the use of the word. The rest  of the media has followed the Times’ example.
                            Whole treatises have been written  about why Trump lies, profiling him psychologically, looking back at his  habit of lying as a businessman when he called reporters and pretended  to be a PR man representing himself. Speculation abounds: he does it  because he can; it’s all part of a grand strategy; he’s clever; he’s  foolish; he can’t tell the difference between truth and lies; he quite  literally can’t help himself.
                                                But what we haven’t done is look at  what Donald Trump’s lies have done to him. They’re backfiring, and he’s  showing signs that he knows they’re beginning to hurt him.
