Poll reliability
Polls are not predictive but rather snapshots at the moment. These all are trusted media-commissioned polls by survey companies. Most of the polls, going back to June, show Trump more than the usual three-point to four-point statistical margin of error.
Secret polling
Political parties, candidates and action committees conduct private polls for internal decision-making. These polls guide media buys and where to channel party funds. These polls are not published, but the polling companies are committed to public corrections of any inaccuracy or distortions by candidate or anyone else.
