This New York Times Upshot/Siena College IL 06 survey was conducted September 4-6, 2018 by telephone calls in English to 512 likely IL 06 voters. This poll has a margin of error of +/- 4.7 percentage points. Calls were made to a stratified weighted sample of voters from the L-2 Voter list via both land and cell phones. A likely-to-vote probability was computed for each respondent based on their stated likelihood to vote as well as by virtue of the imputation of a turnout probability score based on past voting behavior. This combined probability to vote score was applied as a weight along with a weight that considered party, age, race/ethnicity, education, region within the district and gender.
