The state-by-state numbers are based on responses from more than 74,000 registered voters during the period of Aug. 9 to Sept. 1. The individual state samples vary in size from about 550 to more than 5,000, allowing greater opportunities than typical surveys to look at different groups within the population and compare them from state to state.

White college graduates have been loyal Republican voters in recent elections, but Trump is behind Clinton with this group across much of the country, including in some solidly red states.
