The Washington Post tracking poll will be conducted daily until election day. Results are based on telephone interviews with self-identified likely voters nationwide.
The Post and ABC News collect data jointly but use somewhat different models to identify likely voters. This can produce slightly different estimates of candidate support. The margin of sampling error is plus or minus 3 percentage points. Sampling error is only one of many potential sources of error in this or any other public opinion poll. Interviewing was conducted by TNS Intersearch of Horsham, Pa.
This tracking poll is based on a rolling three-day sample. About 350 people are polled each day. To update the numbers, a new day's worth of respondents is added to the sample and the oldest day's worth of respondents is dropped out of the sample.

single-night surveys conducted on Tuesday and Wednesday nights, each
of
which comprised a third of the combined sample.
