A Senate poll commissioned by Raycom News Network indicated that Republican candidate Roy Moore has a double-digit lead over Democrat Doug Jones.

Moore's 11-point lead over Jones is his biggest yet in five polls conducted during the general election campaign and comes two days after a Fox News poll had the race tied.

Moore had 51 percent support among those polled to Jones' 40 percent. Nine percent were undecided.

The survey polled 3,000 likely voters on Monday and had a margin of error of 2-3 percent.

"I think the challenge for the Jones campaign is bigger than what these numbers show," Jonathan Gray, pollster for Mobile-based Strategy Research, the firm that conducted the poll, told Raycom. "Even if he were able to close the gap, how do you turn out Democrats in a state that hasn't had a viable Democratic Party in almost a dozen years?"

Beyond the Fox News poll that had the race tied, two other polls had Moore with an eight-point lead and another with a six-point lead.

Meanwhile, the poll also found that President Trump had a 55 percent approval rating from those surveyed with 45 percent disapproving. The poll said 93 percent of Moore supporters also backed Trump while just 13 percent of Jones supporters gave a positive approval rating to the president.

"Trump's approval numbers are on par for what I would have expected them to be," Gray said in the Raycom story. "I think there are a lot of people in Alabama that voted for Donald Trump because they didn't like Hillary Clinton and I don't think they were ever in love with Donald Trump to begin with."
