Democrat Doug Jones leads GOP candidate Roy Moore by 10 points in the Alabama Senate race, according to a Fox News poll released Monday.

Fifty percent of voters surveyed say they prefer Jones, compared to 40 percent for Moore, who has been plagued by accusations of sexual misconduct.

A similar poll taken last month had Jones leading Moore by 8 points. 

{mosads}The latest poll, which surveyed Alabama voters Dec. 7–10, comes the day before the election to fill the Senate seat left vacant by Attorney General Jeff Sessions.

The new Fox News data is a departure from the RealClearPolitics’s polling average, which has Moore up by 2.5 percentage points. 

According to the Fox News poll, 90 percent of Democrats said they prefer Jones, along with 11 percent of Republicans. Eighty-one percent of Republicans said they prefer Moore.

It is Jones’s best performance in any poll since the primary.

The Senate race has attracted national attention since allegations against Moore of sexual misconduct involving teenage girls were first reported. Nearly 10 women have come forward with accusations that Moore romantically or sexually pursued them when they were teens and he was in his 30s. One woman said he molested her when she was 14 years old, while another accused Moore of sexually assaulting her when she was 16.

President Trump has thrown his support behind Moore, despite the allegations. At a campaign rally last Friday near the Alabama border in Pensacola, Fla., Trump urged his supporters who had traveled from Alabama to vote for Moore.

Trump has also released a robocall in support of Moore, repeating calls for Alabamians to vote for a candidate who will further his “Make American Great Again agenda” and not a “liberal Democrat” like Jones, whom Trump called a “puppet of Nancy Pelosi and Chuck Schumer.”
