Transcript for Trump urges Alabama voters to support GOP candidate

As David said the president may have been in Florida last night but he was eyeing Alabama as David said just on the border there and he was encouraging his followers to vote for Roy Moore. That's right. The president telling the crowd Moore's their man. ABC's Stephanie Ramos continues our coverage. Reporter: While across the border in Florida, president trump fully endorsing embattled Alabama senate candidate Roy Moore, just three days before the election. So get out and vote for Roy Moore. Reporter: Overnight at his rally his supporters -- They're lying. A lot of those women are lying. Reporter: Fired up and standing by Moore. This guy is screaming we want Roy Moore. He's right. Reporter: As trump praised Moore, the senate candidate took to Twitter directly quoting the president's support. This as Beverly Nelson one of the eight women accusing Moore of a range of inappropriate sexual misconduct speaks out. He was trying to pull me -- in between his legs, it was terrible. Reporter: Nelson defending her accusations with evidence, her high school yearbook with the message she says was written and signed by Moore. But for the first time acknowledging she wrote the other note beside that signature. Nelson and herelawyer said she did so to remember how she came to have that autograph. Moore's team denying the allegation claiming he doesn't even know her. We demanded they turn over the yearbook so we could test the ink, testing writing and everything. Reporter: The president who faced 13 sexual misconduct allegations during his own campaign questioning the legitimacy of Nelson's accusations. You know, the yearbook, did you see that? There was a little mistake made. She started writing things in the yearbook. Reporter: Trump making it abundantly clear where he stands. We need a Republican in the senate. We need more of them. Reporter: Roy Moore's democratic opponent Doug Jones is scheduled to be at a number of events over the weekend as he tries to win over as many people as he can. Tom, Paula. All right, Stephanie, thanks for your reporting. I know you have been on the campaign trail, the special election in Alabama and saw the president endorse Moore and RNC came back around. Do you get a sense it's in the bag for Moore. Moore has motivation, somehow overcome these allegations and when you think allegations of child moss little station how could any politician overcome that. He somehow has and denied those allegations. His numbers are good. He has that huge boost from the president and the president is so beloved by Republicans in Alabama, that could be the turning point in this race but as we heard Stephanie report Doug Jones is all over the state campaigning very hard unlike Moore who hasn't made a public appearance since Tuesday but he's hoping for African-American voters to turn out so we'll see on Tuesday. I don't think it's in the bag for Moore. It will be a tight race. We'll have to wait and see. I want to bring in political commentator cokie Roberts into the conversation joining us from South Carolina. Cokie, good morning to you. Let's start right there with Doug Jones. Do you get the sense there's anything that he could do? He's the democratic challenger, to beat Roy Moore in the special election senate race. It would be very, very tough. His hope is to really turn out as Tom was just saying, really turn out that African-American vote. He's got African-American politicians like Cory booker, the senator from New Jersey down there campaigning with him. And hope the white voters who are disgusted with Roy Moore stay home that would be his best hope. And, you know, it's very hard because there's no pattern of people voting democratic in Alabama in recent years. The last exit poll we did there which was in 2012 only 16%, 1-6 percent of white women voted for Barack Obama. So it's going to be a very tough one. More than 40% of people in those polls say they were evangelical, Moore's base trying to turn out. If Moore does win president trump could take a lot of credit for it but when Republicans were fleeing, the pretty stood by Moore's side. If he makes it to the senate isn't the president inviting further scrutiny when it comes to his history with women? Well, all of this situation around sexual harassment with it being so much in the news and now we've got three members of congress having resigned this week alone and who knows what is to come, the president is very much in the crosshairs but he has ridden it out before and gotten elected and is likely to ride it out again unless something happens and, of course, things do keep happening. Cokie Roberts for us this morning. Cokie, thank you.
