A new Alabama Senate poll released Friday has Republican Roy Moore holding a solid lead over Democrat Doug Jones.

Change Research has Moore with 51 percent support to Jones' 44 percent.

That's an improvement from Moore over late November when Change had him with a 49-44 advantage.

The poll was conducted Tuesday through Thursday, sampling 2,443 registered voters with a weighting based on "predicted likelihood of voting in this election." About 74 percent of the poll participants said they voted in either the Democratic or Republican primary. The margin of error was 2 percent.

Undecided voters appear to be breaking for Moore, according to the poll. Change Research said those who have decided who they will support in the past week, 61 percent said Moore. Another 7 percent of poll participants who said they have made up their minds said they still might change it before Tuesday's election.

Overall, the poll said 4.6 percent of participants are still undecided.

The allegations against Moore made by women who -- when they were teens and Moore was in his 30s, said he made unwanted romantic or sexual advances - appear to be having minimal damage, according to the poll. Change said that even if Moore announced the allegations were true, 54 percent of Moore's voters would "probably" or "definitely" still vote for him. Only 21 percent said they "definitely" would not vote for Moore in those circumstances.

Those surveyed were split on whether they believed the allegations to be true: 41.3 percent said they believed the allegations, 41.1 percent said they didn't and 17.6 said they were unsure.

Asked when they made up their minds who they would vote for, 83 percent said more than a month ago. The first allegations against Moore were made in a Washington Post story on Nov. 9.

Meanwhile, poll participants showed support for President Trump. Asked to rate Trump's performance so far on a scale of 1 to 10 - with 10 being the best - 48 percent gave Trump an 8, 9 or 10. Meanwhile, 41 percent gave Trump a 1, 2 or 3.

But Trump's endorsement on Monday of Moore apparently meant nothing to the poll participants - 94.8 percent said the president's support had "no effect."
