If you look at Nate Silver’s latest graph you’ll notice an obvious pattern that began in mid August, which is that Hillary’s support began to wither (except for a brief surge just before her “basket of deplorables” + fainting episode week) and Trump’s began to slowly surge. I don’t know if Trump will land any zingers tonight or whether he’ll bluster his way through and maybe lie himself to death, but I know for damn sure that Hillary HAS to land a few good ones or she’s in serious trouble. At the very least she has to arrest the trend of the last five or six weeks — she has to hold the Maginot line.
