METHODOLOGICAL DETAILS
This poll was jointly sponsored and funded by The Washington Post and ABC News. The
poll is a random sample of the continental United States, not including Alaska and
Hawaii, with interviews in English and Spanish.
This questionnaire was administered with the exact questions in the exact order as
they appear in this document. Demographics and religious identity questions are not
shown. If a question was asked of a reduced base of the sample, a parenthetical
preceding the question identifies the group asked. Phrases surrounded by
parentheticals within questions indicate clauses that were randomly rotated for
respondents. Results preceded by “RV” indicate results among registered voters.
Results preceded by “LV” indicate results among likely voters.
A dual frame landline and cellular phone telephone sample was generated using Random
Digit Dialing procedures. Interviewers called landlines and cellular phone numbers,
first requesting to speak with the youngest adult male or female at home. Roughly 35
percent are completed on landlines while 65 percent of interviews are completed on
cellular phones, including roughly 35 percent among adults in cell phone-only
households.

 Questions 6 and 7 were asked Oct. 30-31 among 659 likely voters; those results have a
four-point error margin.
This survey uses statistical weighting procedures to account for deviations in the
survey sample from known population characteristics, which helps correct for
differential survey participation and random variation in samples. The overall adult
sample is weighted to correct for differential probabilities of selection among
individuals who are landline-only, cell phone-only or dual users. Results are also
weighted match the demographic makeup of the population by sex, region, age, education
and race/ethnicity according to the latest Current Population Survey March Social and
Economic Supplement by age, race/ethnicity, sex and education. Party ID was weighted
to the average of the most recent Post-ABC surveys.
All error margins have been adjusted to account for the survey’s design effect, which
is 1.2 for this survey. The design effect is a factor representing the survey’s
deviation from a simple random sample, and takes into account decreases in precision
due to sample design and weighting procedures. Surveys that do not incorporate a
design effect overstate their precision.
