@snood,
I actually wouldn't be surprised if he did just that.
However, I don't think he's going to lose.
And I'm not the only one.
Last time I checked, Nate Silver, (who is pretty good at this stuff) gave him a greater chance of winning than Clinton. Now, I'm pretty sure he's not ready to predict a Trump victory, nor should he. It's still way too early.
There was some professor or group who, during the primaries, predicted Trump winning by virtue of an algorithm that has only been wrong once (even going back to elections over a hundred years ago - I believe the one race the algorithm got wrong was well over 50 years ago). Unfortunately, I can't find the report, but maybe someone will recognize the one I am referring to. I found it depressing at the time because there was still a chance one of the other GOP candidates might win the nomination. It's still depressing but no more so than a prediction that Clinton will win. This whole election is depressing.
We'll have to see what Clinton's "bounce" is after the convention. It will probably be enough to bring it back to a statistical tie, but if it doesn't...look out Clintonistas!
Here are the two primary reasons I think Trump will win:
Prior to the GOP convention the polls reflected the responses of secret Trump supporters. Why people feel that they can't be honest with pollsters is beyond me, but it's been shown, time and time again that they do. I still think there is a sizable number of voters out there who won't honestly tell posters that they intend to vote for Trump.
The Wikileaks revelations are still to come, and at the very least will only reinforce what a liar HRC is and quite possibly provide scathing evidence of her corruption relative to the Clinton Foundation.
Now if anyone can snatch defeat from the jaws of victory, it's Trump. God knows what he will say before the election.
