Personally I add 5 points to Trumps numbers when I look at any poll. Between the fact Trump is pulling in disenfranchised voters and Bradley Effect I assume he’s easily about 5 point higher than polls suggest.
Now am I just living in a self created delusion? Perhaps, we will find out in November, but polls showing Hillary with any measurable lead just don’t jive with any other empirical evidence out there.
(However, considering a "Trump Effect" and that he's spent close to nothing on ads so far, I'm not discounting the Scott Adams prediction that he'll win in a landslide.)
