Gillum finished with 22.6 percent among black Democrats who said they planned to vote in the primary. Real estate investor Jeff Greene was second with 21.7 percent, former Miami Beach Mayor Philip Levine was third with 20.8 percent, former U.S. Rep. Gwen Graham was fourth with 14.8 percent, and business owner Chris King was fifth with 3.5 percent.
The boost for Gillum follows the airing of his first television advertisements. Greene and Levine have both been spending large amounts of money from their personal fortunes on TV ads and were both ahead of Gillum in support from black Democratic voters in the previous StePetePolls report.
Those new Gillum TV ads might have helped him pull in more support from previously undecided black Democratic voters. The number of undecided black Democratic voters declined from 21.8 percent in the last poll to 11.7 percent in the most recent one. Levine, Graham, King also saw slight increases. Greene slipped 1.7 percent.
Gillum has the longest list of endorsements from current and former black Democratic elected officials in Florida. He also just landed the endorsement of U.S. Sen. Bernie Sanders, D-Vt., which came after the polling dates of July 30 to July 31.
