Leading up to the November election, AP worked with GfK Custom Research and the National Opinion Research Center at the University of Chicago to examine new ways to survey voters.
After commissioning an experiment designed to test new ways to survey voters who cast ballots early, AP updates its findings, using new breakdowns of advance and Election Day voting in the Florida primary.
As early voting becomes more
popular, AP has been testing new ways to more accurately survey the people who
cast their ballots before Election Day, amid increasing costs and declining response rates of telephone polls.
