The third poll released this week shows a major difference in the race for U.S. Senate than the earlier surveys.

This poll, conducted by Florida Atlantic University, shows Gov. Rick Scott with a 10-point lead over current U.S. Bill Nelson. Scott holds a 44-34 percent margin with 22 percent of those surveyed saying they’re undecided.

On Wednesday, the Public Opinion Research Lab at the University of North Florida released its latest survey showing Nelson holding a 48-42 percent lead over Scott, while a Mason-Dixon poll released the same day showed Nelson with a slim 1-point lead, 45-44 percent.

The FAU poll reflects a significant 12-point shift from August of last year. At that time, Nelson led Scott 42-40 percent.

The poll notes that Scott, who has not yet officially announced his candidacy, has seen his name recognition improve from 49 percent favorable in November to 52 percent favorable in the new survey. His unfavorable ratings dropped from 39 percent to 34 percent in the same time period.

Meanwhile, Nelson has seen his name recognition move in the other direction from a 45 percent favorable and 22 percent unfavorable opinion in November to a 40 percent favorable and 27 percent unfavorable opinion today.

The FAU survey was conducted by the school’s College of Business.

This survey was conducted using an online sample supplied by Survey Sampling International and via an automated telephone platform using registered voter lists. There were 750 respondents sampled between February 1-4, 2018 with a credibility interval, a measure of accuracy, of 3.7 percentage points. Responses for the entire sample were weighted to reflect the statewide distribution of the Florida voting population.
