Preliminary data was released Wednesday from a national tracking poll by the University of Southern California (USC) Dornsife College of Letters, Arts and Sciences. It found that 52 percent of those who did not vote in 2016, but plan on voting in 2020, are backing Biden, compared to 32 percent for Trump. A further 16 percent said they would vote for a third-party candidate.

The poll also found that Biden has an 11 percent lead over Trump among all voters. The early results use a probability-based model, one of three methods that will be included when the full poll results are released later this month.
