> The thing about this election is that what if Trump himself is some sort of wildcard that can't really be properly forecasted in the polls?

The only way that would work is if he made people more likely to lie about their voting intentions. Now, there may be something about Trump that makes polling methodologies less accurate (notably, many pollsters have started to take into account education, which turned out to be unexpectedly important last time round) but that points just to bad methodology, not inherent unpredictability.
