There are a few conclusions to be drawn.
First, the way Trump has positioned himself outside of the traditional boundaries of politics will make it unusually difficult to gauge public support for him and for many of his positions.
Second, the allegiance of many white Democrats and independents is difficult to predict — cross-pressured as they are by the conflict between unsavory Trump positions they are drawn to and conscience or compunction. The ambivalence of many Republicans toward Trump as their party’s brazenly defiant nominee will further compound the volatility of the electorate.
Finally, the simple fact that Trump has beaten the odds so far means that it is not beyond the realm of possibility that he could beat them again. If he does take the White House, much, if not all, of his margin of victory will come from voters too ashamed to acknowledge publicly how they intend to cast their vote.
