How the USC Dornsife/L.A. Times Daybreak tracking poll works


The USC Dornsife/L.A. Times Presidential Election “Daybreak” Poll asks more than 400 people each day about their voting intentions. The poll is part of the Understanding America Study (UAS) at the University of Southern California’s Dornsife Center for Economic and Social Research.

Each day’s poll respondents are a subset of the UAS election panel, roughly 3000 U.S. citizens who were randomly recruited from among all households in the United States. Respondents are asked three predictive questions: What is the percent chance that... (1) you will vote in the presidential election? (2) you will vote for Clinton, Trump, or someone else? and (3) Clinton, Trump or someone else will win?


Results are weighted to match demographic characteristics, such as race and gender, from the U.S. Census Current Population Survey and aligned to the 2012 presidential election outcome using self-reported vote in that election.

These charts are updated daily (just after midnight) with an average of all of the prior week’s responses. The Daybreak Poll began on July 4, 2016, and will run through the November election. It is being conducted in partnership with the Jesse M. Unruh Institute of Politics and the Los Angeles Times. For more information about the survey’s methods please visit
