“Add 5% to Trump’s numbers to correct for bias.”

Agree. But then subtract it again to account for vote fraud.
Ah, but in this election there’s a new factor to consider.
Because Trump and his supporters are being demonized in a way that Romney, McCain, and even Bush never were - constantly portrayed as stupid, racist bigots, and neo-Nazis - many are naturally hesitant to reveal their true voting intentions.
This “hidden” Trump support could easily be another 5-10% that doesn’t show up in the polls - but will on Election Day.
