NBC News Exit Poll: How it works and how we use the results on election night
Before votes are tallied on election night, exit polls offer an early look at who is voting and what is motivating their choices.
An exit poll is a survey of voters taken as they leave (or exit) their voting location.

The exit poll also reflects the views of people who voted early or by mail — we take steps to reach those voters by phone and by mail, as well as online.
