On the day before an historic Florida election, two new polls showed Democrats Andrew Gillum and Bill Nelson leading their Republican opponents.

Gillum leads Republican Ron DeSantis in a Quinnipiac poll, 50 to 43 percent, and Nelson, a three-term U.S. senator, leads Republican Gov. Rick Scott by 51 to 44 percent. Five percent were undecided, but only 1 percent said they were likely to change their mind by Tuesday night.

The survey of 1,142 voters was conducted Oct. 29 through Nov. 4 and has a margin of error of 3.5 percentage points.

Those numbers are little changed from the last Quinnipiac poll two weeks ago in which both Democrats led their rivals by 52 to 46 percent margins.

Quinnipiac's Peter Brown noted that Nelson has a 13-point lead among independent voters in the latest poll and "candidates with double-digit leads among independents rarely lose."

Gillum and Nelson also lead among women, blacks and Hispanics in the Quinnipiac poll. Both Democrats are tied with their rivals among men.

Quinnipiac's poll of 1,142 likely voters asked respondents to generally identify themselves. The result was 37 percent Democrat, 32 percent Republican, 25 percent independent, and 6 percent other.

Through Sunday, the 5.1 million Floridians who have actually voted stood at 41 percent Democratic, 40 percent Republican and 19 percent independent or other.

In a new NBC/Marist survey, Gillum leads DeSantis and Nelson leads Scott by identical 50-46 percent margins.

The poll, conducted Oct. 30 through Nov. 2, questioned 917 registered voters, of which 595 were likely voters. It had a margin of error of 5 percentage points for likely voters.

Among likely voters, President Donald J. Trump's numbers were upside down, with 44 percent approving of his job performance and 51 percent disapproving.

Scott's numbers in the poll were similar, with 42 percent of likely voters viewing him favorably and 50 percent unfavorably. Nelson was narrowly above water, with 45 percent viewing him favorably and 42 percent unfavorably.

In the governor's race, Gillum was viewed favorably by 48 percent and unfavorably by 40 percent, and DeSantis was viewed favorably by 43 percent and unfavorably by 45 percent.

Twelve percent of likely voters said they had never heard of Gillum or DeSantis and had no impression about either candidate.
