"Trump’s advantage in online polls compared with live telephone polling is eight or nine percentage points among likely voters."
=>"Former Tom Bradley Aide Says Secret Trump Voters Similar to ‘Bradley Effect’"
So this is a telephone poll, 8-9% of Trump supporters hide from human pollsters, Trump just started TV advertising on Friday, Olympic women's beach volleyball was over on Thursday. (Coincidence?) and it's a little less than 2 weeks until Labor Day.
If Trump didn't know something about marketing, he wouldn't have become a billionaire. No cause for panic. (Yet.)
Not believing that reverse Bradley effect. Not in one’s own home. Sitting on one’s own couch, one isn’t going to lie about whom they plan to vote for.
