The show's producers revealed the massive finale voting push in a statement released in the hours before Tuesday's show -- but it did not say who was getting the lion's share of the fans' votes.
"Due to a record amount of activity, some viewers reported experiencing difficulties registering their votes for the 'Dancing with the Stars' finale, which affected each finalist equally," read the statement. "The issue was promptly addressed and voting lines remained open online until 11 a.m. ET on abc.com."
Both Palins, mother and daughter, have denied any organized vote-getting tactics.
Sarah Palin was in the audience cheering on her daugher during Monday night's performances. On Tuesday, she was in Phoenix signing her new book.
"She's had the journey of, you know the challenge and the improvement and the work ethic," Sarah Palin told ABC News' John Berman after her book event. "This has been all about work ethic and perseverance and, you know-- No, I couldn't be prouder. She's happy. She's very happy."
Just as online audience voting closed this morning, Joy Behar predicted on ABC's "The View" that if Palin wins the competition, "there is going to be a scandal."
Judge Carrie Ann Inaba told the Wall Street Journal that Palin's continued presence in the competition was a "shocker."
"My theory is that she represents the every day girl, and the interesting part of the show is that you've got this girl next door who's obviously not a celebrity and not a performer out here running neck and neck with an R&B singer, a guy who's got his own TV show, and Jennifer Grey, and I feel that people are living vicariously through her. They're like, I get it, she's like me," she said. "But still, it's a shocker."
Despite Palin's huge vote support, some fans are upset. Very upset. Last week, a Wisconsin man shot his TV with a gun, saying he was fed up with Palin's subpar dancing skills and politics.
On Monday, however, Palin roared out for her first dance, a jive, earning straight 9s.
"You were, last time, a gorilla and now a thrilla," judge Len Goodman told her, referring to a past episode in which she and her partner danced in gorilla suits. "Vast improvement. Well done."
Later, Palin earned two 8s and a 9 for her freestyle performance to a song from the musical "Chicago" that she began while dancing in a cage.
"I have to give you credit for aiming so high," judge Bruno Tonioli told her, echoing the other judges. "You did very very well, but not quite at the level that this song required."
Grey, who consistently has been among the top scorers, earned two perfect 30s. For her second dance, she picked a song from "Dirty Dancing" -- "Do You Love Me."
On his first dance, Massey matched Palin with three 9s.
"That feels unbelievably, unbelievably amazing," Massey said.
He pulled four judges' points ahead of Palin with his second dance, earning two 10s and a 9.
