So suppose that we call the debate a draw. Suppose, furthermore that the tape the Post published didn’t damage Trump. Instead, let’s say the polls look about the same a week from now as they do today, with Clinton holding a 5 or 6 percentage point lead. Maybe Clinton’s numbers were a little inflated after the first debate and Trump has even gained a point or two, somehow.

That’s still a fairly awful position for Trump with time running out, undecided voters getting off the sidelines, early voting already taking place in many states and little or no ground game to help provide a strong finishing kick. There’s the third debate, but without an extremely strong performance in that one, Trump is probably left hoping for an “October surprise” or a big polling error (not impossible, but it would have to be larger than the 4-point margin by which Brexit polls missed).

Or, obviously, things could get worse for Trump. And some “October surprises” — such as further leaks of tax returns or embarrassing comments caught on tape — could work against him. (They also wouldn’t be that surprising.) His attempt to make an issue of Bill Clinton’s past, which his campaign seems determined to pursue, could also backfire.
