A Nashville singer-songwriter, McDonald has been touring the country trying to hit it big. Could he make it to the top of "Idol?"
Mansfield could see him going all the way or flaming out early. He's that unpredictable. Halperin agrees. With his crazy outfits, his chicken dance and unique voice, he's hard to pin down.
That said, his looks and style have already won over "countless women," Halperin said, especially the older female viewers who make up a large part of the show's audience.
It also doesn't hurt, Mansfield said, that he looks most like the past three winners, David Cook, Kris Allen and Lee DeWyze.
The Glamberts' Revenge: James Durbin
There's no doubt that Durbin, the Santa Cruz, Calif., rocker with Asperger's and Tourette's, is reminiscent of season eight runner-up Adam Lambert. Both Lambert and Durbin have commented on their similarities.
It's possible that all those Lambert fans, known as Glamberts, still miffed that he didn't win could throw their weight behind Durbin. "It would be nice payback for the Glamberts," Halperin said.
Mansfield puts Durbin in the top 5 but doubts he can win. "I don't know that a rock singer is going to win this show," he said. "I'll believe it can happen when I see it."
The Dark Horse: Lauren Alaina or Haley Reinhart
Mansfield thinks child country music prodigy Alaina from Georgia could win even though early favorites usually falter.
First, he said, she'll have to learn how to take criticism. And it's possible the other country crooner in the competition, Scotty McCreery from Garner, N.C., could take her out.
For Halperin, the dark horse is Reinhart, even though she was in this week's bottom three and most people will disagree. She said the 20-year-old student with the amazing voice is still finding her footing. But once she does, "she could really wow us."
