Exit polls are conducted by Edison Research for the National Election Pool on behalf of a consortium of media companies: CNN, ABC, CBS and NBC.
The polling locations were themselves selected through random sampling, meaning the resulting interviews should be representative of Election Day voters across the state or nationally.
In addition to the national exit poll, there are also exit polls conducted in specific states with key, competitive presidential or down-ballot races.
Even so, exit polls are still polls, with margins for error – which means they’re most useful when treated as estimates, rather than precise measurements.
That’s particularly true for the earliest exit poll numbers, which won’t yet have been adjusted to match the final election results.
