The campaign of Democratic U.S. Rep. Gwen Graham is circulating a new internally produced poll that shows her opening a commanding lead in the Aug. 28 Democratic gubernatorial primary.

The commissioned survey from Democratic pollster ALG Research shows Graham shooting up to a 16-point lead over her nearest rival, former Miami Beach Mayor Philip Levine. That compares to a four-point lead ALG found for Graham in a July poll, and a 10-point deficit to Levine in a June poll.

The ALG Research poll, taken July 29 through last Thursday of 800 likely Democratic primary voters, found 33 percent ready to vote for Graham; 17 percent for Levine; 13 percent for Palm Beach businessman Jeff Greene; 10 percent for Tallahassee Mayor Andrew Gillum, and 3 percent for Winter Park businessman Chris King.

Undecided is down to 23 percent of likely Democratic primary voters, for the ALG survey. That was at 40 pecent last month.

The poll, for which ALG is claiming a 3.4 percent margin of error, is consistent with other recent polls showing Graham rising lately to become the clear Democratic front-runner, and shows her with the widest lead yet reported. The live telephone survey was taken during a week that wasn’t particularly good for Graham, with a statewide-televised debate in which she was repeatedly attacked; and when Greene and The Collective ran TV commercials attacking her.

The poll gave her the highest name identification, 74 percent; and the highest favorability rating, 65 percent. It also found her leading among men, women, white voters, black voters, in every age bracket, and in every media market.

Graham also showed improving and now strong marks among Democratic primary voters when they were asked what they thought about her chances to stand up to President Donald Trump; represent their values; experience to be governor; and leadership potential. In every case she got at least 63 percent agreeing, while last month her numbers were seven to 11 points lower on each question.
